Here is a much more in depth and accurate definition of the word: ": a person who strongly and unfairly dislikes other people, ideas, etc. : a bigoted person; especially : a person who hates or refuses to accept the members of a particular group (such as a racial or religious group)"
But even your own citation includes racism, homophobia and sexism. Not to mention that Judaism isn't a race. It's a religion: which goes under idea. I guess you could call me a bigot who hates other bigots then. I am a lot like a Nazi in the sense that I want to burn things I see as weak, and nobody is weaker than somebody who has to hide behind a majority status.
Then we have differing ideas of bigot. When I refer to jews I usually refer to the jewish racial group, but you are right that i am intolerant to those of the jewish religion, communist opinion, stalinist opinion, and maoist opinion, and homosexual opinion.
