That's obviously not true. For example, this woman confessed to making up an sexual assault allegation for political purposes:

>One of Justice Brett M. Kavanaugh’s accusers admitted this week that she made up her lurid tale of a backseat car rape, saying it “was a tactic” to try to derail the judge’s confirmation to the Supreme Court.

And we know that at up to 10% of rape accusations are provably false. The real number of fake accusations could well be higher.

>Lying about sexual assault in court is perjury and jeopardizes victims as much as the defendant.

So what? If I make up an allegation against you, there is little risk to me unless you can PROVE I lied. But if the "evidence" against you is just my word, what can you do with that to establish that I am lying?
