I have more errands to run before I can focus on this but this isn't intolerance of a person, this is intolerance of peoples intolerance towards my species being the way that makes me happy and makes me comfortable.
Well, there you go. It doesn't make you comfortable to include queer people. Ask yourself, though, why is this? Why do you have to exclude us, why do we make you unhappy and uncomfortable? That's exactly why people oppose this idea, artists will get away with blatant homophobia and we will be able to do nothing about it.
As for your definition of homophobia, that's not what it means now. Sure, it may have started with a literal definition like that, but it's now become a term to describe those who are intolerant of queer people or uncomfortable with their existence. Please don't try to red herring this, we aren't here to talk about the evolution of a word.
Anyway, moving on to the oppression bit. The reason people don't like to listen to white, straight, cis men is because they are the oppressors. They should have little voice in most social justice issues, because literally nothing affects them. They're told to shut up because their voice always rings the loudest, no matter what it's about, even if it shouldn't. White people aren't hunted down and killed for their skin, straight people aren't sneered at and bullied relentlessly for being straight, cis people aren't constantly misgendered or killed for being cis. When people on the internet say things like "all white people need to shut up" white people are not harmed. When people on the internet say "no one cares" in response to a man, it's because they're angry that men get all say. But, again, no harm is done to the man. In the real world, no one cares if you're cis, a man, white, or straight. No one will bully you for that, and therefore you are not being oppressed.
And being vegetarian is something that is deeply ingrained in a lot of people. They CAN eat meat, and that sense it's a choice, just as much as LBTQ+ people CAN technically date someone of a sexual orientation that they don't prefer.
Also, please just stop with this argument, I'm sick of seeing it. Queer people are not like vegetarians. End of story. Being a vegetarian is a choice, being queer is not. I don't get the second half of that statement, though. What does vegetarianism being a choice have to do with someone queer dating someone of a gender they aren't attracted to?
