I always find myself bemused by people who begrudge paying their taxes... I have always considered taxes to be the dues paid by people who wish to belong in a healthy, civil society. I usually end up having to pay Federal, NY State, and City of Yonkers taxes, and I make small voluntary contributions to several of the N.Y. State funds (two cancer research funds, the missing and exploited children fund, and the wildlife conservation fund). Yeah, making a couple of sizable payments is not exactly fun, but that's part of being a mature adult, and a responsible citizen- it's holding up my end of a rather good bargain.
My advice to the Tax Day Teabaggers, grow up and pay up.
I'd say nut up or shut up, but that would be an infringement on their First Amendment rights.
