What's up with batman and the erasing of queer history? Sry I try to interact with fanon as little as possible
There is no simple or short answer to this but to try and not make it a wall of text - Batman/Robin has always been a staple of the queer community, so much so that to this day there are "brudick" graffiti in big cities and lots of older gay couples have been using them as a reference for solid partnership which endures in spite of adversity.
Originally there was no indication anywhere that Bruce and Dick were in the roles of father and son, rather they were partners against crime, one the shadow of the other, and they would share everything both when it came to crime fighting and in their everyday lives. They're shown sleeping together, going on lake trips together, finishing each other's sentences and Dick being viciously jealous every time Bruce would "replace" him with any of the women he used to have flings with such as Talia or Selina.
Did DC mean for them to be read as a queer couple? No, of course not. Bob Kane and others wrote a partnership, an unbreakable bond which would allow these two men to overcome any obstacle together, and queer people read into it as queer people always do.
Someone else read into it though: Frederick Wertham, who called Batman a pederast and used Batman and Robin as an example of how the evil comics would corrupt young minds to send them on the way of perdition and sin. He wrote all of this and many more infuriating shit in his book Seduction of the Innocents, which was then the major influence in creating the Hayes Code, which is the reason why we never had queer characters in comicbooks and movies and anything really for decades (and we're still struggling today).
Wertham and the Hayes Code did not stop the queer community from loving Batman and Robin though, therefore what started happening was the more subtle shift towards Bruce and Dick having a father and son relationship rather than a partnership. You can see this clearly with Jason Todd for the first time: Bruce takes Jason in and treats him as his own son, the narrative calls them father and son, and there is no doubt in the mind of who's reading that Bruce perceives Jason as his child. It all went steadily downhill from there.
Nowadays, writers have Dick say character assassinating things like "I love you dad" to Bruce, Tim saying "we will save our dad" to Damian, and everyone in the fandom acting like this has always been the case and actually you're weird and you should be sent death threats for shipping Brudick, because "UMMM that is literally his son?!??!?!?". DC has been pushing the idea that these folks are a nuclear family for a while now, but whoever has actually read the comics knows it's not the case, and it used to be very different before.
Brudick, among queer people, used to be entirely uncontroversial. While Wertham raged about how it corrupted the minds of young men and the Hayes Code prevented queerness to be anything but vaguely hinted and coded in the text, queer folks didn't care and kept having matching Batman and Robin shirts.
Today queer people will call you a pedophile and a groomer and try to doxx you for posting Brudick art because apparently they're doing the fascists' job for them, either because they are genuinely misguided or because they think that if they're enough morally pure they will have a spot among the chosen ones, hell if I know.
What I know is that they'd suck Wertham's cock and balls if he wrote Seduction of the Innocents today, and it's DC's fault too with their erasure of every found family dynamic among the batclan, and the way they've been pushing the idea of a "batfamily" instead, in which everyone has a strict role of son or brother or father, and shipping them makes you the antichrist.
