A common complaint that I've heard throughout the ages is the whole "I don't have a problem with it but i wish they wouldn't shove it down out throats" kind of reasoning. This could explain some of the responses to this whole thing. I think what a lot of non queer/LGBT <insert any letters I've missed here cause they are always adding new ones> people struggle to realise is that from the other side the typical heterosexual norm (if you will) is literally constantly being shoved down everyone's throats at all times. Even something as simple as the standard assumption that everyone is straight. Queer people never just come out the once, it's something that has to be constantly reiterated, i guess some people's response or rebellion to that is to become much more overt and unapologetic about it, which, great, you do you.
As a younger gay man i placed a lot more importance on my sexuality than i do now, generally i think there's (hopefully!) much more interesting things about me other than who i choose to fuck but i totally get someone who's a bit younger feeling kind of stifled like that wanting to shout it from the rooftops. The furry thing i'm less keen on because in all honesty i find it kind of weird and maybe that's my prejudice showing, the only thing i'll say about that is that i came to that conclusion by hanging out with some furries at a furmeet so maybe it was them in particular that makes me feel this rather than the fandom as a whole. But hey, if he's not hurting anyone who really gives a shit, anyone who doesn't wanna see gay or furry things doesn't need to follow him.
