Ok I painted Atheist with a broad brush but I'd argue that most are anti-God.
Why would an agnostic be anti-God? Agnostics don't hold a position on the topic. They think there might be something to intelligent design they just aren't sure.
You example sucks!
Because I don't support a certain group of people makes me a bigot? Then what does that say for people like you who say we're bigoted because we don't agree with your abominable lifestyle? Wouldn't that make you a bigot also?
Agnosticism is a label for those who aren't convinced that there is a supreme being or isn't. It is the only rational position because there isn't enough evidence one way or the other. To go from insufficient evidence to a decision that there is or is not a supreme being requires something else and that something else is not rational. It is emotional, or delusional, or some other thing, but it is not rational. Agnostics are anti-religious, sometimes, because faith requires that one disregard logic, evidence, reason, critical thinking, open-mindedness, and sometimes even humanitarian morality. They don't tend to be anti-atheist (to mean here as one who has faith that there is no supreme being) because in one way we are united. I disapprove of beliefs that concern absolute "T"ruth. No one knows what absolute Truth is.
Intolerance for people for who they are is unjust and bigotry. Intolerance of intolerance is just.
I tolerate religious people. I will not tolerate religious people seeking official favoritism for their beliefs, usurping science in school, shaping social policy with unfounded religious beliefs such as relegating homosexuals to second class citizens or in any other way encoding their beliefs into law and thereby forcing all others, religious or not or of different religions, to conform to their religion. Christians don't want Sharia law in this country, agnostics don't want biblical law in this country. Either would violate our 1st Amendment rights.
Religious people can pray and worship wherever they want except in government because it gives the appearance of official favoritism to religion. There are no nonbeliever organizations who are attempting to do what religious organizations are: encoding discrimination into law.
