This is a one way street. The left only excused misogynistic behavior from other leftists—they’ve always used allegations of some sort of sexual misdeed against Republicans.
The problem for the left is that the accusations seem pretty credible against their politicians. Bill Clinton and numerous members of Congress paid off their accusers, which is tantamount to admitting the truth of the allegations. On the other hand, the allegations against Republicans in most cases seem contrived and overblown. We are to believe that a man in his 30s asking teen girls on dates is the same as rape, or that a host of a beauty talent show looking at a scantily clad contestant is committing the most egregious kind of sexual harassment. Nevermind the complete implausibility of the claims... the forged yearbook signature... etc. Also, it seems that with these claims, the left does not credit us with any ability to weigh each case on its merits, much like they expect us not to be able to tell the difference between illegal alien and legal immigrant.
