What's the point of male spaces when women will just barge in?

Why should I even make an effort to save anything for myself or find a space that is only for me? Even if I manage to find something that is completely mine, some selfish woman will just tag along and take it away from me. I find this to be the case for male-only hobbies, male-only relationships, male-only places, male-only everything really. I have no desire to be around these entitled creatures yet I can't escape them because they will just barge in and "invade" spaces that they don't really care for. They do this because they think we deserve to lose our male spaces, since they can't have their own female spaces because of us.
