A true Republican wouldn't even give a homeless guy the time of day.
The only ones I have ever acknowledged are the ones who say "Excuse me, I'm not asking for money, please listen to me for a second and take a look at this paper." (he was distributing a homeless activist rag in San Francisco).
That was pretty smart of him. All he had to say to get me to treat him like another human being, was to not ask for my money. Because face it: you could give a homeless person $100,000 and it would be gone in a year or less and they'd be back where they are now. What's $20 or $50 going to help?
