First of all, asking for money without offering a tangible service in return whether it be panhandling or fundraising is unrelated to what the government does unless the panhandler holds a gun to your head while he asks you for money.
And yes, the kids are taught that "the community" owes them something by their braindead public school teachers just because the school doesn't get new imacs every semester.
But does the fact that the kids use public streets and foolish court rulings mean that we must be less than polite? I would argue no. The government forces me to call out those idiotic "cable marker" guys who tell where I can and cannot dig in my back yard, but I don't feel the need to treat them like dirt while they're there. These people are essentially powerless, so whats the thrill in mistreating them? Law enforcement officers, on the other hand...
