I try hard not to judge, as really one never know's when you might yourself be in this situation through circumstances beyond your control

Yes some are homeless by choice, but I think that is the minority of people.

Regardless of the situation they are still HUMAN BEINGS, and that is what I try to tell myself, so yes I do think we need to help these people, turning our back's on the problem is not the answer or humane thing to do IMO, thanks.
