I don’t recall the media worrying so much about other, left wing protesters. Most of them were bussed in and paid to participate in the “cause of the week”.
Why the dire concern about where “normal people” come from or why we are so pissed off?
The reason why they bus people in is because they are on the losing end of an issue. When the Proposition 209 was a hot button issue, our Republican club had the school ban people who were not students. We were on the winning side when the left did not their big guns. in addition, we had “scouts” within each group and they would feed us tactical information on what they had planned.
