I have little to no interest in most of the political threads, whether they're in D&T or elsewhere. But I'm not offended/bothered by them occurring in D&T, even though the forum's not explicitly for that.
For a time on ASPD I stayed away from posting in HDH because I thought politics was all the forum talked about and I didn't feel like I "fit in". I worry that other users feel the same, sometimes, but there are obviously plenty of other topics discussed in D&T -- more variety, I think, than HDH had.
So, move 'em somewhere else, keep them allowed in D&T... either is fine by me.
