I dislike all religions with equal ferocity, so consider that when reading this response.
You are all missing the point. In America it is absolutely your right to believe what you want, and I believe all religions are fucked and causing the downfall of this country. What is not your right is to discriminate against people in the marketplace due to race, religion, gender, sexual orientation, etc.
Infidel, what would you do if you were told you had to accept less money because an employer decided that, despite it being your Constitutional right to bear arms (and your years of training in that field), they have a company stance against people who bear arms. They would never tell you to disarm (its your Constitutional right, after all) but you would no longer be eligible for raises regardless of qualification.
After all, it is generally accepted that the major source of gun violence in America is perpetrated by people who bear arms.
I think its the same with this religious intolerance. Lowe's is not telling the family that they have to change their religion. They're not saying that they should change. What they are saying, though, is that their religion is the source of their refusal to support the show.
Having a problem with the entire religion of Islam is fine in my book, seeing as how I have a problem with every organized religion. However, one of my best friends is a devout Muslim, I have very religious Christian friends and even some friends that are in what I'd call a cult. They are my friends because they're good people and I don't judge their character based on the religion they associate with.
Bottom line; hate a religion all you want. The moment you start hating a PERSON because of their religion, and not by the content of their character, you are in violation of everything America stands for, and frankly, you can fuck right off.
