First, why did you need to screencap this post and them post it that way? It's so hard to follow along to like tht as compared to a normal text post.
Gerg isn't a decent guy. In fact, just recently, he made fun of Jefree Star being molested as a child. No decent fucking person does that, not even as a joke. Being raped/molested isn't funny. It's gross of Gerg to even try and make a joke about that. But, even if he does try to apologize, it's not sincere since he wouldn't have done it if he didn't mean it.
People are rude to him because he's an asshole. Not because he's a funny asshole, just because he's an asshole. He goes out of his way to attack people. Just look at his ignorant videos about black people's hair that he made recently, too. He's stating that as fact when it's clear that he didn't really do much in the way of research. He didn't ask any actual professional hair dressers (much less black hair dressers), he only cherry picked forum answers that benefitted him, etc. So, when he talks about things like self harm or cutting, it's coming from a place of ignorance, at best.
He's never cut himself. He's never self harmed. So, by your logic, he shouldn't talk about it. But he is and he's misinformed himself and convinced himself that is he degrades those who have self harmed and cut themselves, that he's a fucking champion and that he's saved millions when.... that's not really the case. He really hasn't saved anyone. He's hurt far more people than he's helped and there are a lot of former fans who have said that his stances on things like self harm and eating disorders have hurt them and made them relapse or just get worse. Full disclosure: I used to self harm (not cutting) and I still struggle a bit with an eating disorder and, fortunately, I never fell into Gerg's trap but he has enraged me with his shitty opinions that he tries to play off as facts.
His warning were always bullshit to dodge any sort of accountability. He got called out by his detractors and felt that, to counter that, he needed to put a "disclaimer" on his videos so he wouldn't be called out (which backfired in his face.) We detractors called him out on him saying that his opinion was fact, when it wasn't. He never really provided any actual credible sources to back up his claims. It's always shitty biased shit. Nothing from actual doctors on the best way to handle people in general suffering from self harm or eating disorders. Spoilers: it's not harassing them until they stop self harming or until they eat something, that just makes it worse and he hasn't realized this at all.
Just because someone hasn't self harmed, though, doesn't mean that they can't talk about it. If they're actually trying to help and not being a dick about it and covering it up as "tough love," then that's fine. I know people who have never self harmed and they have done the best that they can to help those who have and that they talk about it becuase they have done a great deal of research on the topic and feel confident enough to speak up about it and be supportive. Lots of people have opinions on things that they've never gone through, though.
But, instead of listening to a D-List youtuber, maybe try and go to a doctor if you think that your issues are bad enough. Talk to an actual doctor and ask them if what Gerg is saying is healthy or not. Then, talk to them about any issues you're going through (self harm, anxiety, depression, etc.) and they can help you far more than this hack can.
There are worse people out there, you're right. But, people are multifaceted and can focus on calling out multiple shitty people at the same time. The way he goes about things isn't healthy. He gas lights people, he bullies them, he's manipulative, he is an incredibly toxic individual. He is not a person you should be looking up to.
.... Onision victims? I mean, we detractors have just wised up to his bullshit and see right through it. He is the kind of person to tell you all these sweet little lies and never follow through with it and then get offended that you thought that he would as he's saying that he never promised anything and laughs at you and pins averything on you. That's what he's done to his numerous exes. That's what he's done to his numerous former friends. He's obsessed with getting back at them for what? All of his own mistakes and his own feeling of disappointment that he lashes out at everyone and that's why everyone fucking leaves him, lmao
