Who doesn't want to look at the evidence? I'm happy to look at evidence, and readily acknowledge that discrimination exists.
That discrimination is nowhere near as severe in its effects nor as pervasive in its practice as the discrimination against black people in the 1950s, and no one without an inflated persecution complex would attempt to pretend that it was. Even though isolated and sometimes egregious acts of discrimination against atheists can be cited, and the Boy Scouts and the military are still forces for systematic discrimination against both gays and atheists, atheists today do by and large enjoy equal rights under the law. The same Constitutional guarantee of freedom of religion that protects the rights of Baptists and Quakers secures the rights of atheists as well.
From what I've seen of the self-styled atheist activists in this thread, the goal is not equal treatment anyway. Who, other than a snarling misanthrope completely devoid of social skills, would think that equal treatment would be encouraged by characterizing the religious majority as stupid and evil? Martin Luther King didn't sneer "White people are my bitch" from the steps of the Lincoln Memorial. Gay activists didn't erect billboards saying "Heterosexuality enslaves genitalia."
Rather than trying to fight discrimination, they seem to be in a war with religion itself, employing tactics which seem deliberately calculated to alienate as many potential allies as possible among the religious majority. I can understand how those who won the hearts and minds of the Vietnamese people with arrogant abrasiveness and smug superiority might be reluctant to abandon such tactics. After all, they were smashingly successful in the 70s. Still, I can't shake this nagging feeling that there just might be a better way.
