1) You've come into a thread that is specifically looking at men's problems, and made it about feminism and your own highly female-oriented viewpoints: "As a feminist", the (justifiable) fear that people make this out as "men's problems are more important than women's problems", "allowing women to be strong and independent, I think we also must allow men to be weak and to ask for help if they need it.".
If people came into a thread about sexism in the work place and explained an opinion with similar words with flipped gender, they would be criticised.
2) For the worse, the terms you pick out yourself have been coopted by an unfortunate group who use them to push their own agenda, who go around with mugs marked "Male Tears", gleeful in the support of a minority of people abusing the term and the quiet tolerance of many more. They don't represent feminism or progressive values. But they do use the words most loudly, and that develops unfortunate connotations.
Overall, your points may be valid, but your expression of them alienates the people this article is about and addresses.
But some people don't want to see a reasonable counterbalance. They see a word they don't like and downvote without reading; they actually get angry when others fail to live down to their stereotypes. Going in the other direction, I've seen liberal feminists get confused and angry when they meet a conservative who supports GLBT rights. It makes people uncomfortable when folks don't stay in their pigeonholes. It's frustrating.
It's not accepted to derail a women-centered discussion with "but patriarchy hurts men too!"; why do you expect anything less in derailing a men-centered discussion with "but feminism is for men too!"? Granted you're not being That Guy in the usual direction. But you're no less being That Guy for it. Maybe consider not being That Guy.
Just like it's annoying for someone to chime in with "what about men's XYZ!" in a conversation explicitly about women, it's annoying for the inverse to happen.
While you're 100% right and gender roles (patriarchy) mean we're actually having the same conversation I would love to be able to have those two conversations independently without descending in to whattaboutism and explicitly gendered language.
> But yes, in allowing women to be strong and independent, I think we also must allow men to be weak and to ask for help if they need it.
Men have this problem precisely because they are "strong and independent". Not pressuring men to work constantly to the point of isolation is not the same as "allowing men to be weak".
