Understand that some or most of the key posters there are literally pawns of Russian or Chinese intelligence. Troll farms, wumao, what have you. Whether they are literally government employees or contracted through a third party, their purpose is to astroturf positive optics of their employer and negative optics of the US/the West as a whole. A more sinister interpretation, they are trying to destabilize the West by doing things like trashing Biden, now Harris, hoping to secure a chaotic and inwardly destructive Trump presidency.

Anything they say is to service these goals, anything they believe is mutable to these goals, and nothing they argue is in good faith.
