Irrational, sure. However,
- the article specifically refers to people who call themselves male feminists having hurt and abused women under that pretext ,which is a way smaller subset
- the matter isn't "individual men have harmed women", it is "'man' as a social class fucks over women (and men)". Distrust is, in my opinion, more understandable when it's the latter.
And honestly, people aren't entitled to trust and thinking otherwise is, well, entitled as nobs. If I, a Finn, tried to enter a Sami space as a Sami advocate and got treated with apprehension, I wouldn't think "those uppity Sami are being unreasonable" because Finland as a nation and Finns as a group do fuck the Sami over on a structural level.
For me, the article comes off as "listen to the people actually experiencing the thing instead of assuming".
