You'd be wrong on basically every point you made here. Employment laws in most states will not protect the type of scenarios I put forth: your political, religious, and sexual views are not protected in most states throughout the country. That's assuming they are foolish enough to list the true, controversial reasoning for firing you instead of listing any of the innocuous but prevalent employment violations that almost every employee in the country is guilty of. You could sue and you would lose: as someone who recently went through this in battling anti-LGBT bigotry at work, I'm painfully aware of the limits of employment laws in most states.
Ever found a picture of yourself at the bar that wasn't taken by you?
I'm beginning to wonder if some of you are even reading what you're quoting. I've made it quite clear that my positions and opinions in this thread have absolutely nothing to do with racism and everything to do with the precedent of allowing employers dominion over our personal lives under pain of termination.
Whether or not I can argue the merits of gay marriage, euthanasia, or religion should have no bearing on whether or not my employer could terminate me for having an opinion contrary to theirs.
