Allegations of "Victim blaming" are a classic tactic to shut down discussion by implying that anyone who steps out of the appropriate mental box will be deemed an accomplice.
Seriously, if you are the victim of a false allegation that is later proven to be false, then your reputation is not destroyed. If you are the victim of one instance of a false allegation that later reveals a pattern of bad behavior, then you should not have behaved badly in the first place.
