Because the latter virtue signals to idiots at low cost. Polls go up hopefully because some people support the current thing.OK I'll bite, if BLM and Antifa were Russian psyops why, in the age of harmless-yet-Russian things like musicians, cats, movies on streaming services, etc getting Canceled, wouldn't blatant Russian-backed subversion be absolutely crushed by glowies?
Meanwhile the former would royally piss off all the far left people the establishment has deals with, so the lower class leftists would riot and the upper class leftists would call them fascists in many op-eds all around the mainstream media.
Polls would go down, considering that they are relying on the votes and volunteer support of such people now, so can't just kick them to the curb because they make a mess sometimes, nor because someone else gives them some hard to pin support because they like the mess.
Considering where the polls are now, the establishment absolutely needs them to go up, not down.
You are implying that the glowies are in charge of the establishment politicians and media and get the last word, as opposed to merely having deals with them.
