Private security guards with bikes separated the pro-Palestinian group from Israel supporters, and UCLA eventually added metal barricades after counter-protesters repeatedly tried to breach the encampment and in at least one case witnessed by The Times entered and shoved a woman to the ground.
Creating fear of losing your job or school place, stifling free speech for political gain, and gaslighting are psychological abuse and are used frequently in hasbara.
They’re using those tactics at UCLA. Look at this guy…
Aaaand Block is stepping down. Crazy how much behind-the-scenes power the Israel lobby has, and little they regard anyone but themselves.
