He's 15 and will be 16 later in the year. This is the internet. I doubt he gives much of a fuck, I don't know why you're being so anal about this. Telling people to treat him differently because he has mental health issues and a limited social life is silly, he's clearly a functioning human being so he should be treated the same as everyone else.
Aaron is no stranger to reporting things he finds offensive, which is fine, but that whole thread is full of shitposts, I doubt he cares, but I don't want to speak for him or on his behalf, I hardly know him and neither do you.
If he is offended, let him deal with it himself. Jesus Christ.
