I also forgot to add this part:
As much as it's true that there is always some culture war going on about something that might or might not be acceptable to say, as in all wars I think people should think "legitimate targets only". So you don't go making public attacks against private people, and preferably you should focus on people who are more or less actively promoting an idea, not just commenting on it offhand.
And more focus on actions please, less on words. So more talk about
people who actually commit domestic violence for example, and
less about people who just say stupid stuff.
