what's the deal with guys who insist on sitting with their legs spread far apart even when they're like sitting in coach on an airplane and there's fuck-all leg room in the row?

Also this thread manages to completely ignore the real villains; the capitalist space hoarders who don't provide ppl enough room to sit comfortably on various forms of transport.

i am not a large person but i find the CTA seats (especially on the newer trains, which are awful) uncomfortably small. there have been instances where someone will attempt to sit down in the seat next to me and more or less sit directly on my leg.

i have to sit like this to fit in the seat even on the airplanes that supposedly have more legroom than the norm

I've had this "discussion" w/my gf. I cross my legs alot (which can be even worse space-wise and I avoid it on crowded transport) but is it cool if my knees are no wider apart than my shoulders? Sometimes the nads are sensitive and prone to pain. I don't want to be the db who imposes on someone else's space but can I get credit for a couple extra inches of knee space for appendages that womenfolk don't possess or is that bad? God knows I've had some bosoms (and God knows what other appendages) pressed into my back on crowded evening buses and I've made exceptions for things which aren't voluntary.
