Good point
Dan Stubbs.
The Chinese govt will threaten family members if any of them speak out negatively against the govt, even when they are in America, far away from Chinese oversight.
You are right this is uncanny and scary how the left has started the PC police, and threatened to dox or confront/harass political opposition in public for their support of Trump or other unpopular beliefs, that they class as white-racist or anti-LGBT etc.
I don't think this is from Russian or Chinese influence.
But the political pack and pecking order mentality influences
these hierarchical groups into acting this way - divide and conquer by social politics.
It is both within human nature to socialize in this way,
as it is part of human spirituality and development to
RISE ABOVE this pecking order/herd mentality and
seek to organize and harmonize between tribes to
achieve higher peace and justice for all humanity, not just one's local tribe or nation.
