It's all a time investment thing and the line is subjective depending on how much value you want to throw into the idea.
So, if you wanna believe in something, I sure hope you consider that what you believe in will lead to a benefit in your life.

That's my 2cent about anything like that.

tldr; there's people who's into furry because it leads to drawing, socializing, creating animations, designing, talking about various topics etc.
So, as long as the reasons lead to somewhere good then it's cool.
