Well, there's no rule against being a leftie around here; there are a few who hang around. You probably will catch flack for a while, though, being a leftie with a recent sign-up date (we've had a real problem with trolls, and some folks are a bit itchy with the trigger finger, so to speak), but if you can put up with that, hopefully you'll be able to stick around.
Who knows, maybe one day, you'll be a "convert". Or at the very least, enjoy some good discussion, even if you disagree with most of the folks here.
I might have to DUFU a new edition today. This one is slowing down although it has thus far garnered over 24,000 views. A record by far.
