Nearlly everything you mentioned will not get downvoted in discussion section. Indeed direct discussion of polyamory for example has even been seen on Main. The only one I can see downovoted "liberalism vs. libertarianism" (what no one remembers us reactionaries running around here?), but that is because of the "politics is the mindkiller" norm. If you think we can preserve high quality of discussion on OT when it comes to politics, why haven't we been able to do so when wearing our rationalist hats (see any gender/sex/feminism/PUA thread ever)?
Huh? I thought you were a conservative, not a reactionary, seeing as you're generally cautious about change and not really advocating the superiority of some historical social arrangement. With the sole exception that you're for dictatorship and against democracy, but there's plenty of quite modern dictatorships, as you recently pointed out.
Petition: LW should introduce a dedicated off topic area
Why?
1) I want to discuss various topics with people who are both intelligent and rationalist, and i know of no other place where to do it.
2) If find that rationality is getting boring in itself. I need to use it on something.
3) As stated in this comment http://lesswrong.com/lw/btc/how_can_we_get_more_and_better_lw_contrarians/6e3p
the narrow set of topics might actually hurt LW by driving good rationalists away.
