Long ago, I wrote about how Trayvon Martin brings out the worst in people. The rabid hate aimed at the unarmed African American 17-year-old killed by George Zimmerman sullies the soul. The vicious internet campaign that peddled a photo of then-31-year-old rapper Game as an “up-to-date” picture of Trayvon was disgusting.

But just when I thought it couldn’t get any worse, enter Dinesh D’Souza.

I won’t waste time on the bio of the acerbic conservative who has made sport of criticizing President Obama and questioning his loyalty to the United States. You can read all that you need to know here. But I’m writing about him because of a wildly offensive tweet he sent Tuesday afternoon.
