In plenty of cases it's absolutely self evident (especially when there are plenty of historical precedents for similar or analogous situations).

Yes you can get involved in extended arguments with people arguing in bad faith or whose world view is fundamentally incompatible with your but that's usually just a waste of time (I mean you wouldn't argue with Nazis either just the same as with people trying to institute a Stasi style surveillance apparatus through slow boiling)
