When is a "holocaust" Not a "Holocaust" And causes a Minor holocaust?

Here.

Short version:

Rep. Alan Grayson...was less than 24 hours removed from his caustic Republicans want you to “die quickly,” speech, and now he was making holocaust references on the House floor.

“I apologize to the dead and their families that we haven't voted sooner to end this holocaust in America,” he said Wednesday.

It touched a nerve, and made some in his own party uncomfortable.
