probably not. first it would be a waste of moderator's time and labor, since there's wreckers and reactionaries on this website. second, threads are made up of multiple ongoing conversations that people are free to engage in, setting the tone as they go along. third, one thing is banning reactionary talking points or requesting that our users make use of content warnings, another entirely is to curate the entire website's conversations on personal preference.

taken together my overall experience is that i've read several 'serious' and informative comment threads, as well as many 'unserious' ones. they did not impede one another, even as they are freely shared. the news megathread is a prime example of it. people will occasionally discuss history, theory, politics, even as things cool down for weeks entire and people just chill.
