I like them, I've liked them more than most people for as long as I remember.
But I also perfectly understand that not everyone does, but as for the people who
hate them and start
raging the second they see a picture of a cartoon animal....
The problem is that people refuse to let go of their incorrect belief that the furry fandom is nothing but a loveual special interest, and they use these stereotypes and generalizations that they hold on to to make even the most innocent pictures seem horrifyingly deviant, and attack anyone who posts, draws, or even likes them.
Not to say some furries aren't at fault for the hate either - the ones who go around shouting FURRY PRIDE, doing stupid stuff, and whining that no one likes them - deserve all the hate they get, and need to shut up, but people should stop judging the entire fandom off a few freaks.
fad
Animals have been anthropomorphized since early human history.
The fandom itself started in the early 80's
That's not a fad.
But I don't want to go to a con in a fursuit
I don't plan on having a fursona
and
yiff
that's just plain nasty
Having fursonas are common but the other things you listed are a small minority.
No one is making you do these things.
