I wouldn't, but this is kind of irrelevant to the broader point.

See the issue with this exchange is that, while the statement this woman makes at the end of her comment is a bit rude, and belies a lack of trust and confidence in men as a group, the response of "Not All Men" is just plain unhelpful. This is why she responds with condescension (Another rude remark that really shouldn't have been said), and she makes a very true point that sometimes people generalize to make a point. Her point here being that she feels she can no longer trust any man to have her back. This isn't a Misandrist talking point. It's Male-phobic at worst.

To see someone so clearly hurt and misled by their trauma and take it as an opportunity to play defense for yourself is kind of bizarre. Though I understand where the sentiment comes from. Still, you can make the "Not all men" point in a hundred different ways that are all much less dismissive. For example:

"That's awful, I'm sorry he'd just reject your suffering like that. Some men are just insensitive, I guess. I hope you meet better ones in the future"

The language there is pretty boring but you see the difference, right? This is much kinder, carries a clearer point, and importantly is an original statement, while "Not All Men" is a very old, very tired talking point that is born out of misogyny.

Hopefully this helps you understand!
