Threads being pulled off-topic is an eyesore. It's part of how sections become about the same 6-8 people posting about the same topics time and time again and it makes it very clique-y. It being commonplace on TiBB is what is making it more unwelcome for other folk (not just right-leaning) to post in SD, because they don't want to end up in the same exact arguments all over again.

As long as it is held consistently, then I don't have any issues with that rule and I think it should be strongly enforced. I don't think deletions is necessary though. If it's just a few posts, then a mod can post (bold text and all) a reminder to stay on topic... if it goes sideways, lock the thread or move posts out to a new thread. If it's a real trouble user, then issue a short ban.

If it's a discussion you want to have, then start a new thread. There's no reason you can't link the other thread and start from there. I think that's a pretty fair compromise?
