While the rationale behind manspreading is perfectly valid, to single this problem onto men is just plain ridiculous. This has nothing to do with gender, it's simply a matter of public etiquette. If a girl spreads her legs out while the bus is jam packed with people, people would be pretty pissed too.
Do not listen to any feminist suggestions. Instead, every man and human should simply stick to this guide:
1) When the bus/
metro capacity is under 25%,
spread your legs as you so desire
2) When the bus/metro capacity is 25-75%, generally spreading is fine as people have other seats to choose from
3) When the bus/metro capacity is over 75%, it's best to play it safe and tuck your legs because people will likely want to sit in the adjacent seat

leg spreading
Me: You know what misses me off so much? When people leg spread
on the bus. There was this guy who freakin' blocked two seats with his legs on the bus. Like, I ain't gonna complain about that if the bus was half empty, but the bus was full and there was
an old lady who wanted to sit down but the guy was too busy on his phone to notice her.
Her: Don't you mean manspreading?
Me: No, I mean
leg spreading.
