That was not the topic under discussion. If you want to go down that rathole, then start with the full facts. Romney paid 14.1% in taxes. He deducted 2 million in charitable contributions, other wise his rate would have been 19.6%. As a side note he made an additional 2 million in charitable contributions for which he did not claim a deduction. Between income taxes and charitable contributions, he paid 43% of his income. Now give me the comparable number for $250,000 ~ normal exemptions and deductions for a family of 4.
Charitable contributions are not taxes.
