Well, to be fair, New Yorkers are something of a special breed of asshole to begin with. :lol:
What is a major problem in NYC is not necessarily a major problem for the rest of the country.
Secondly, even the presence of signs doesn't necessarily indicate that the problem is severe in and of itself. This is a democracy, and a rather spazzy one at that. Even the mere perception of a problem can be enough to sometimes result in bureaucratic overreaction, as the powers that be scramble to appease the masses.
That's not to say that NYC, or other areas of the country, might not legitimately have a problem, of course. I'm simply saying that the circumstantial evidence we have available at the moment really isn't enough to definitely indicate that this is the case, at least not to the "societal" extent that the Feminist Left likes to claim.
Catcalling is virtually non-existent in most of the Southern cities I've either lived in or visited, for example.
In Charleston, the most I've ever seen were a few incidents of drunken frat boys shouting things at people out of moving cars while driving through the College of Charleston campus downtown. Frankly, even then, they were just as likely to shout at men as women, and their comments weren't usually sexual in nature.
