I started to become interested in feminism over the last few months, but with the last horrifying cases of crimes against women i saw that many feminist women have (reasonably) learned to fear us, or at least, have some resentment towards us (again, reasonably), so, do we have a place in this movement, or we should take a step aside
If one has a belief that feminism is a necessary and effective movement, one is obligated to work towards the goal of the movement.
This may or may not be the same thing as participating in specific groups, communities, or actions.
If a given segment of the movement doesn’t want to include men in their activities, respect that and work in other ways.
You’ll likely find that when it comes to taking action, be it via protest, awareness raising, etc, it is very unusual to be excluded. Where you’ll run into exclusion is more on the discussion and theory side of things. And obviously, don’t try and intrude on support spaces.
