exactly. and it's actually the simple litmus test i use to figure if someone can participate here. i don't see it as my job to censor posts (a very rare thing) or to govern what folks wish to talk about. just to remove posters who won't submit to a culture of sincere, on-topic (ie non-poster-or-moderator-centric) discussion. this culture is the thing which i value and seek to protect.
someone comes here and harms this value - out they go.
for all the justifications one hears from the folks who have been jettisoned, i have never banned anyone for another reason. and i have never missed anyone i have banned.
