I can't say that having 18+ things means its bad, or even the 18+ things are bad.
None of it should be judge.
If people dress up as furries and yiff around, that's ok as long as they are safe
If people draw artwork of pornagraphic scenes, that to is ok.
If people incorporate being a furry as part of their lively hood then kodos to them for being so confident in their choices and lifestyle, I couldn't do it.
Regardless of why you became a furry, whether art, philosophy, acting, dance, belief, or just appreciation, no matter what, it shouldn't be seen harshly, any of it.
It's its own world that has splendidly been brought together by countless peoples imagination, beliefs, views, skills, etc.
In the end the fact that this world exists purly by us, I think it's remarkable and beautiful and by being confident and content in such, regardless why, is worth admiring.
