I'm getting strong vibes of post-9/11 fervor, just with a slightly less obviously racist veneer (still racist, though). People in this state of xenophobic groupthink would absolutely support violence against China and there would be zero barrier to manufacturing their consent for debilitating sanctions, covert operations, and proxy wars. China's relatively strong position will preclude anything too direct for a while, but please consider that this will probably be the central international tendency against which we (members of the imperial core - apologies to comrades outside of it) must organize.
Please consider joining your local socialist organization(s) and taking part in their anti-war/international committee.
I think they're a pretty good barometer for the 20-40 year old American dude demographic.
Their sinophobia wouldn't translate to personal action but that's kind of a danger in itself. They only need to be passive for serious violence to happen.
