Half of that community is either barely a legal adult, ot not even from what I've heard from someone that claims to be furry.
Ofcourse this person also spends a lot of time criticizing that community.. I feel it's full of shit personally, but maybe that just adds to my point.
If the youngsters are into fucking animals, and pretending to be one as well.. Well their ideas do stand the greatest chance of making it to an interplanetary civilization.. but It'll probably be another 1000 or so years AT LEAST the way things or looking so theres also a good chance something even more disgusting and stupid will become popular.
