To answer the question directly, yes. Supporting those who support evil causes is something we will have to answer for. Though terryk is right, it is often more complicated than that.
I think being forced to support social programs through taxes is not what was intended as "charity". I also believe that the vast majority of the social programs out there are only creating more problems. If the tax funded social programs only supported those who were truly disabled and in need, I would support them. But I have seen FAR too many lazy people abusing the system and leeching off of the rest of us. "Glut themselves on the labors of others."
And I agree with a-train, I voted Republican not because I think they are the good guys, but because I believe they are simply the least evil. I was lured by the Constitution party, but I threw my vote away on Ross Perot years ago and realized I helped get the candidate I disagreed with most elected.
