I find thoughtlessness doesn't follow gender lines. I think we just tend to notice more the stuff that bugs us most.
Of course I've seen guys manspreading, but if I take the seat next to them, they move their legs as needed.
I find women by far to be more guilty of putting their bags on the seat next to them. Also they tend to cross their legs, which means everyone has to dodge them getting on and off the train, and if I'm standing in front of them, I have to figure out how to avoid their jutting foot.
