Here's some nice controversial things for you:

• Given functional birth control and non-fucked family structure, incest is fine and natural and probably a good experience to have.

• Pedophilia is a legitimate sexual orientation, even if it expressing it IRL is bad (which it is not). Child porn should not be suppressed (tho some of it is documentation of crime and should be investigated).

• Most of the impact of rape is a made-up self fulfilling prophesy.

• Child sexual consent hits the same issues as child acting or any other thing that parents can allow, and should not be treated differently from those issues.

• Self identity is a problem.

• EDIT: most of the deaths in the holocaust were caused by the allies bombing railroads that supplied food to the camps.

Less controversial in LW, but still bad to say outside:

• Race, class and subculture are the most useful pieces of information when judging a person.

I run out of ideas.

EDIT: in case it's not clear, I take all these ideas seriously. I would actually appreciate a discussion on these topics with LW.

EDIT: this was productive! I've seriously updated one way or the other on many of these ideas. Thanks for pointing out truths and holes everyone! :)
