Why yes, absolutely. I do not know if this is lucky or unlucky, but I don't know (personally and outside of the internet) anyone who isn't a pacifist in some capacity when it comes to foreign policy, and in full capacity when it comes to domestic struggles. It just isn't done. Symbolic violence such as flag-burning or, if it comes to that, car burning, is perfectly okay. So is strong language... as long as said language doesn't appeal to violence. We don't joke about being violent to our opposition, unlike, say, American pundits and talk show hosts. Again, it just isn't done.
Just to clarify: do you mean to restrict the scope of discussion to voicing support for large-scale/political violence? Or do you also mean to say that you are all radically averse to violence in your personal lives?
I have found this most wonderful (if fairly lengthy) article, and thought you would enjoy having it brought to your attention.
It is so good, I think we should include it among the references in the "Politics is the Mind Killer" wiki page. But, before that, I submit it to you, and ask you: is there anything in this article that would warrant its exclusion from this site? I mean, besides the fact that it is about politics, and written by a notorious Social-democrat (And is that in itself grounds for exclusion?).
