I try to keep in mind that a lot of people in these threads are just shitposting and moving on with their lives, not necessarily demonstrating a major personal investment or serious vendetta against the concept on display. If I were with a random non-furry GAFfer in real life and happened to see someone out and about with a tail, I imagine that I'd be able to have an intelligent conversation with that GAFfer about what they don't like about it, why it's harmless - generally something more moderate and reasoned than the reaction-gif/one-sentence status quo. It's easy to judge and pigeonhole when it's just someone depicted in an internet link or in a sweeping OP that just asks "what's the deal with X group of people?" and paints that group as abnormal from the start. I'm certainly not excusing shit posts, and I wish people would consider that their words might be discouraging others from expressing themselves, but I try to have faith that it wouldn't happen the same way in real life as it does online - and that people's actual human interests and tolerances might be a little more nuanced and accepting than the persona they present to the world in responses to garbage threads like that.
That said, no, I didn't read it because the earlier thread about the girl who thought she was a cat bugged me even more with the responses it got.
