New to MR, and curious why so many feminists are so quick to label all MRA's as misogynists and sometimes political radicals, but never actually address the issues brought up?

I am slightly left of center politically, a non-Christian who finds a lot of what Men's Rights advocates have to say solid, factual and legitimate. Indeed, from what I see, MR's are an extremely diverse group of left and right politicals, with varying views on many subjects. And like most MR's I am certainly not anti-woman by any stretch. But when I have read some feminist sites, when they actually talk about MR, I find they tend to label MR's as right wingers or woman hating bigots or sexist players. Rarely do they ever address the very real concerns of men, but moreover, view MR's as an enemy (like r/againstmensrights) instead of a group to find common ground with.

Am I wrong thinking that feminists are against MR's because of the privileges and power over men they stand to lose?
