Jumping into these "reactionary" mens rights positions as a counter to feminist issues is the wrong way to do it and understandably makes people a bit angry. Just as in if real life someone is telling you about an issue - countering with a "buuut, group Y has it bad too..." would probably make someone double take a bit. It's unproductive, but normal on social media because it's engaging and creates a hot comment section.
In my opinion some major male problems are related to:
* Mental health, suicide and the lack of services and support for men.
* How the education system works better for females than males.
* How platonic relationships with males have been systemetically decreasing.
* How in rural societies women are more likely to move to the cities and get an education leading to men having way less romantic options.
If you bring these topics up with women they'll probably sympathise and maybe also agree that these are issues that our society should be assisting with solving. How it should be "solved" may be up for debate. But framing it as a counter position to the feminist movement isn't the right way to do it. But very normalised online, which feeds into my point of the internet exaggerating issues as most debates you see online is controversial by design of the algorithms and content creators trying to get engagement.
Disclaimer: I'm from Norway, which gives some context. But I think these issues are pretty common across the westernized world.
