It's true that African slavery spanned several contents, but it started in Europe. It had been a European trend that the 13 colonies, which were a group of colonies formed by a European nation, had established, of which over half disagreed with slavery and did not allow it within their borders well after the Revolutionary War. Yet we still treat all white Americans like they're responsible, even those who grew up in states that weren't even around during the Civil War, let alone the African slave trade. Oh it doesn't matter if there are some people that know better, most don't, and our schools are apparently having a hard time getting it into kids heads that such was the case, because the vast majority of them will still tell you "it's the White Man's fault."
Excuse me? I'm going to take offense to that. It's American culture. It's not just African American, it's not just a minority American culture, it is American culture. If it was just African American culture, it wouldn't be as widespread. Otherwise, for half of the obscenities that's on any one rap song, it would be illegal to play on any radio station or be sold in any stores as technically it's hate speech, sexist, and supports anarchy. If you took the lyrics of any one rap song, put them in any other genre of music, and had anyone else but an African American sing that song, it'd be lucky to even be released let alone be on radio. We see that kind of bs pulled on every other music genre, but not rap. Hmm...I wonder why...oh that's right, I know why; because if anyone did, they'd get the racist card pulled on them whether they meant it or not.
Put it into perspective really quick. You stated that there are groups in the rap and hip-hop community trying to paint a picture about Afro-identity, society, and oppression. Let me tell you something; until you pointed that out, I was not made aware...and to be frank, before hand, I didn't even care to look. In the reality of things, most people don't. It's why half of our world's problems exist, because of people jumping to conclusions without looking into it closer. It's why I hate modern society in general. But in reality, most people don't bother looking for an external message. Most people listen to the music because they like it, they like the beat, they like the rhythm, and that's it. I'm one of the select few that actually pays attention to the lyrics first before I decide I like a song; that's why I don't listen to rap, because getting my ears to bleed from all the "fuck that bitch" and "bust a nut in that cop" and "smoke dat crack" and so on and so forth is not something I'm into, and let's be frank; that's most of the rap genre in the last two decades as a whole, stereotypes aside. But most people don't care. I can guarantee that 99% of the college kids and highschoolers dancing off in clubs to the beat don't care either, and they're the ones you should be worried about. They're the ones who are going to grow up thinking that policemen are assholes, girls are bitches that need to know their place, and that all there is to life is getting as much money as possible by any means necessary, regardless of what race they are.
There is nothing nice about tolerance. As a white, right-wing Catholic from the Pacific Northwest who was raised in a conservative household and happened to like Dinosaurs as a kid just enough to learn about science, evolution, and discover just how verbally violent our world can be, I can guarantee you from experience that there is nothing nice about tolerance. People hate it; it is in our nature to eliminate something different if it is going to be a problem to our status quo, regardless if our status quo was not very beneficial to begin with. It is why a country like ours should not conceivably exist in any fashion whatsoever, because we have so many different people with different status quos expected to get along under the same government that eventually it will come to a head. We don't live in the 14th and 15th centuries anymore; there is no new world we can run to to escape this anymore. Persecution will happen, on either side, and eventually it will get to the point where one side will try to violently one-up the other, until it either assimilates or goes away permanently, as is our nature. The only non-violent solution is tolerance; tolerance and compromise. And not compromise like "You get to say yes to this issue, but I get to say yes to this other one," no no. Compromise in a way that neither side is completely satisfied; where at first glance it will never seem like it will work but eventually people can get used to it and thus benefits both. Such compromise can only be done when spearheaded by a third, unbiased party with no immediate opinion on either side of the argument. Every first world problem that we currently have can be solved this way and be out of our hair with ease; everything from racism to prejudice and oppression, to gay marriages and transgender, and even whether or not an airport can put up a Christmas Tree and not have to worry about getting sued. The fact that we don't do this infuriates me, because every single problem that we cry havoc about on the news is pointless...pointless...in comparison to the bigger picture. In due time, we will eventually run out of the funds, oil, energy, and resources to be able to be considered a first world nation, and everything will fall apart. By then, all of this; even this text that I'm putting up; will no longer matter. No one will care about whether or not so-and-so issue is legal or so-and-so action is offensive. We will be too busy trying to survive off of what is left to even notice.
And I apologize for that long winded last paragraph, but that is essentially my view on all of this. You can try to convince me otherwise all you want, but I honestly don't care. In the end, our argument is a first world problem spearheaded by people who refuse to see the big picture and won't stop until they are satisfied and their opposition eliminated. Such is our nature, such is our hubris, such is our demise.
