Yeah, from what I remember, many of the conservatives who left this place did so mainly because they started getting trolly with their posts and the conversations delved into personal attacks and stuff like that. If a member of this board knows we have LGBT posters here, for instance, and starts going on about how sinful and horrible gay marriage is, they shouldn't exactly be surprised when those gay people, as well as those who support same-sex rights, get upset at their comments. Same goes for people who say that anyone who isn't Christian, or who's pro-choice (I remember a LOT of abortion debates on here in the past that got awfully personal and upsetting), or whatever, are to blame for the downfall of our nation.
There were indeed conservatives here that I had wonderful debates with that I could name right off the top of my head, because they never made things personal, or got trolly with their comments. That sort of behavior is what's led to a lot of people (on both sides-there's a lot of liberal posters I remember who don't seem to be posting here anymore, either) to leave. Their political affiliation had little, if anything, to do with it.
(Case in point: saying this forum went "full retard" probably won't help endear people to your argument. I agree we've had some debates here lately get way out of hand with the insults and so forth, but there's better ways to make that point.)
