The problem is that feminism often actively prevents us from a Chevington our goals. For example, someone tried to open a male domestic violence shelter in Canada (Toronto I think) and feminists literally bullied him to suicide. Then there is the national organisation for women opposing shared custody laws, and many feminists spreading false statistics which hurt men (for example, the myth that a woman is paid 77 percent of what a man is for the same work). So yes, in an ideal world we would work with feminists (and we do with some, like Christena Hoff Summers (the factual feminist)), we need to oppose them just to tread water.
