i don’t answer questions (present thread excepted). i insist someone say plainly what it is they are getting at. and if they refuse that’s that. if they persist in asking, i tell them not to be petulant. and if they present an argument, and it’s sound, i usually just let that stand. if it’s unsound, i let them know.

and, of course, one of the best ways is to never take a strong position yourself that can be sealioned.
