Taxable Winnings

Well I just a tax form in the mail from my TVG account and everytime I get one I get so pissed. First of all, I do not think gambling winnings should be taxed because you are winning money that has already been taxed. But what really burns me is that I am going to be taxed on $754.00. I think I should only be taxed the difference between $754.00 and $600.00. So my tax responsibility should be $154.00. Man, this just burns my chaps.
