"Bigot" is a great word to apply to a political opponent. After a successful application of the word, the person so accused can no longer make any arguments and is effectively silenced. It's why leftists love to use the word. As can be seen here, TBR is not immune to the tactic.
I do not use the word lightly.
According to Webster's, a bigot is "a person who is obstinately or intolerantly devoted to his or her own opinions and prejudices; especially : one who regards or treats the members of a group (as a racial or ethnic group) with hatred and intolerance."
I think that definition fits pretty well for a fair number of those around here who constantly spout off about Islam, or immigration, or what have you.
And I'm going to name it when I see it.
