Having wide hips and a butt that spreads when I sit I'm probably just as bad for taking up room as a guy manspreading, I can't really change that tho like a guy could close his legs a little. I have more of an issue with the width of seats especially ones with arms as I often get kinda wedged, a couple of years ago watching an Eagles tribute band at the interval came the mass exodus for the loos and bar. Being a bigger woman I let most of our row shuffle past me before standing up, when I stood a whole bank of six seats came with me, so embarrassing.
The public transport thing isn't so much of an issue for me, locally anyway, it's a quiet part of the world and seats are usually plenty. Travelling with my hubby on public transport usually means we can't sit together tho with me being big and him also being a big guy it's just not comfortable, again being quiet we can usually find seats with a table and sit opposite which is ok but often a leg room issue sometimes.
Personally if a guy has room to spread that's fine as long he's not encroaching on someone's personal space, I do find myself being conscious of my size sometimes tho, c'est la vie.
