The first argument is easily defeated: We get taxed the hell out of our work, get taxed when we buy goods, can get taxed when we sell goods. We are taxed when our taxed money makes profit....

Yet many of us that still can afford it after being taxed pledge to the homeless and people in need, pledge to families struck by catastrophes and many more.

Second argument is a bit harder to defeat because the mechanism is somewhat different. But when you take German catholic church as an example it is easy to say that they only care about other people if they get the tax money I mentioned earlier. They get the tax money to care for those other people that most probably wouldnt be in need of help, when they wouldn't been taxed earlier.

I bet every member of a city parliament knows what I am talking about.
