Coworker inadvertently bashes me and my shames me for being gay.

There is this one big guy at my work who will say interesting comments. He’s literally the epitome of fragile masculine uneducated man.. sad and pathetic He won’t ever directly address me, but for example today he said, “I could never be friends with a gay person.” “They are just wrong like, I only like the opposite of me.” (By that he means he likes women... okayyy?) I was in the same room like wtf. It’s hard to write down here everything he says, but he says things literally about me, like there’s about 10 of us who work there, and I’m the only gay person. If you can imagine a bunch of stupid comments a pathetic straight guy would say, he’s said it.I don’t want to address him, because technically he never says my name or anything, he’s speaks generally about gays or whatever, but it’s so dam obvious. But also he’s a big black guy, and I’m a little 18 year old boy, so there’s a little intimidation there. (also he’s like 30) This guy will say these things in front of everyone, even in front of our boss, who is also a man. So like even my boss doesn’t care, and I feel silly telling my boss how i feel, he’s like 21 so he’s young and dumb like the rest of them. My fellow coworkers notice this too, so I’m not the only one. I feel like if I do tell, his argument would be, “oh, I wasn’t even talking about him...” or whatever..A part of me just tells myself to ignore him, he’s not worth my time. (I’m quitting in like 2 months to go to college) But, then there’s another side of me that wants to be strong and not be disrespected and be a bad bitch or whatever lol. Plus even if I did confront me, likes he’s literally so stupid, he’s been a dishwasher for like 10 years there, and idk, can you just picture that stupidity. At times it makes me sad and feel worthless, but I remember who I am, and who HE is.....So, what do you think? I’m not even sure what answer I’m looking for here, I just wanted to let this out and share it.. thanks :)
