Los Alamos
Thurman Talley suggested (5/16/13 Los Alamos Daily Post) any 501c organization that made political contributions should lose its tax-exempt status.
At the risk of seeming obstreperous, I’ll make a bolder suggestion. Although charitable and religious organizations themselves should not be taxed, perhaps donations to such organizations should not be tax-deductible.
Why should other citizens collectively have to pay more tax just because I choose to donate to my favorite charity or church?
