What do you mean by "incest is natural"?

Looking at the comments, seems like a lot of people think this is an incest kink sub, but I really don't support that. I'm only interested in incest because of the way society treats people who are attracted to the same sex as them. I think that's absolutely outrageous, so I support incest to bring down the laws and teach the world a lesson.<br><br>It's not rocket science to see we have a lot of these people in the comments. So I wanted to know, what do you mean by "incest is natural"?
