@Cycloptichorn,
Cyclops, you are wrong on that. Federal income tax and FICA, which I would include as an income tax, accounts for 93% of all federal income, according to the following site. Income tax receipts total 59% and social security receipts account for 34%, totalling 93%.

You could argue that FICA is not an income tax, but it is taken from every wage earner, based upon their income, so it is merely another form of income tax. Also as a self employed individual, I pay it on the same income tax return as I do income tax. Also consider the fact that the government does accounting tricks to borrow from the fund to spend, so it really functions as just another part of the income tax system for all practical purposes.
I believe it is a very fair question to ask everyone in this country if they are paying their fair share.
