So not "extremely common" as the commenter upthread said.
> liquid left on seats
As in, something spilled?
> litter
Lol. Only on a weekly or monthly basis?
> gag-inducing smelly people
I think some people are looking to be judgmental.
> antisocial behavior
That's taking it pretty far; it's easy to ignore these things which are almost always harmless - none have ever affected my life. Maybe being judgmental and (for some) hateful is the real and dangerous antisocial behavior - the consequences have had real and awful consequences for many.
> not put up with that
That's a bit controlling, insisting the world and other people must be your way. Freedom means something very different. No wonder you don't like NY.
