Bialik got in trouble with the PC crowd a couple of months ago. She seemingly blamed Harvey Weinstein’s victims for not being modest enough. The PC crowd really raked her over the coals.
This could be Bialik’s attempt to get back in their good graces.
She also caught some flak from the PC crowd recently when she made a donation to the IDF. At the end of the day though, she is a hollywood leftist who doesn't want to be seen as biting the hand that feeds her, so her pendulum needed to swing back to the left. This incident was the perfect opportunity for her and the other hollywood hypocrites with their armed bodyguards to do some virtue-signaling.
