Yes, I think so too. My caution is against aiming anger everywhere and thereby doing worse than nothing. (If people were in danger of aiming anger nowhere and thereby doing nothing, I would also caution about that. But, realistically, people tend not to write a lot of Medium posts saying, "You know, I'm not angry about anything and everything is fine.")

I wouldn't necessarily take your post above as representative, but do you notice that you make no distinctions at all in the entire post about good vs. bad behavior?

It's all implicit, if it's there at all. You explicitly acknowledge nothing. The explicit message is men = bad. That's it. Maybe a few men will get upset and be even more negatively disposed towards you and/or women (since you claim to speak for women). Mostly it's a wash.

If this is your standard presentation, you are giving up tremendous discriminatory power in your anger. Surely some actions and attitudes are better than others. Surely some men behave considerably better than others. Don't you want to motivate people to better actions, better attitudes, to be better people, so things get better?

It's very hard to do that if you don't frequently draw clear, explicit distinctions.

Feeling injustice also doesn't help change anything. You have to actually provide leverage against the bad and towards the good. On social media, praising the good and condemning the bad specifically is the best tool you've got.
