Of all the absurdities in modern feminism this has to be the dumbest because, like any argument that pretends to purity it is ultimately self defeating. It's the same problem the Catholic church has with its pedophile priests.

Catholic doctrine states that 'priests are holy men doing God's holy work on earth'.

'how can he be holy, that one's a convicted pedophile?' you say.

The church has two choices when they hear this, let their entire doctrine collapse or pretend they didn't hear you and repeat 'priests are holy men doing God's holy work on earth'.

So you point to another pedophile, and they repeat 'priests are holy men doing god's holy work on earth'.

After a while it becomes a joke, but inevitably people stop laughing at the joke and start laughing at the comedian (the church itself). When that happens they have lost all credibility.

The 'believe (ALL) women' who say they've been raped argument has the same flaw.

When you point to an accusing woman and say, 'Yeah, but she's a liar, there's video evidence that what she says happen DIDN'T happen' the feminists reply, 'believe (all) women'.

You point to another woman who is a proven liar and the feminists respond, 'believe (all) women.'

It's already gotten to the point that people are laughing at the feminists because they claim a purity that doesn't exist, and this robs them of all credibility because instead of denouncing liars they are supporting them.
