Attacking people is generally a no-no. But if you HAVE to attack someone, you might as well do it with glitter. And it might as well be for Gay Rights.
In fact, such thoughts have already been acted upon.
Valid points brought up in this video include:
"Stop anti-gay politics. It's dividing our country, and it's not fixing our economy." And "Feel the rainbow".
In the end, it seems Gingrich DOES learn from this experience, as his muttering of "nice to live in a free country" is the right amount of sarcastic, as if to say, until we (the people) have equal rights, this country is in fact, not free.
