From Insty I see this, about the situation in Hong Kong:
Pro-Beijing agitators are attacking random passers-by and fomenting brawls and riots in the shopping malls where pro-democracy demonstrators gather to sing. The… police are cooperating with the pro-Beijing agitators, arresting pro-democracy demonstrators, but leaving the pro-Beijing agitators alone.
Now where have I seen this kind of thing before? Oh, I know.
Just substitute “Antifa” for “pro-Beijing agitators” and “Trump supporters” for “pro-democracy demonstrators”, and you have… Portland.
