The language is important.
I think MRA can get dished out too easily, but think it's important to have.
For me it's the difference between someone caring about issues that genuinely affect men (eg raising issues about male mental health and suicide, toxic masculinity, challenging the boys will be boys narrative etc) and someone who feels the need to act like men are the biggest victims in the world, whatever happens to women happens to men but worse, men nasty women, feminists hate men, you women should be nice to poor men, men should have a veto over abortion because it's his baby too etc.
Similar to the difference between someone campaigning quite genuinely about issues affecting trans people (eg gender dysphoria, access to talking therapies, ways to navigate spaces where a third space would be appropriate, how to balance competing rights, sexual assaults on trans women in sex work, violence in relationships affecting trans people etc. All very valid areas to focus on), Vs aggressive TRAs who want to shut women up, whatever oppression you face as women we have it worse, we want access to your sex segregated spaces, rewrite language, put up or shut up or we'll threaten you.
It's really important to be able to make a distinction between these different positions.
I dislike handmaiden, but find it awful just how many women aren't just oblivious to the patriarchy, but are there reinforcing it by telling other women to roll over, be nice, don't discuss things beyond nappies and cooking because we should realise how lucky we are to exist in a world of poor men.
