Well duh.
The point is not that what Weinstein did is OK because some Republicans are also bad, but that any Republicans using this to smear Dems while at the same time supporting people like, you know, the President, are full of shit. (cc: Sean Spicer, Don Jr., etc.)
And how many of these dudes were out there demanding that Republicans condemn the fact that Roger Ailes was doing debate prep with Trump after he was forced out of Fox for sexual harassment?
And tbh I haven't been looking very hard, but are there even many liberals defending Weinstein? Silence, yes. That's bad in its own way, but I don't know who is making excuses in the vein of "locker room talk" besides his lawyers.
Sexual harassment and assault are bad, period. If there's a group this reflects poorly on, it's Hollywood, not Democrats. People trying to turn it into some partisan thing are grasping wildly for some 'both sides' takes.
