Actually it is your situation.

I'll assume for a moment that you're from the United States. The disaster on 9/11/2001 was religiously inspired. The current conflicts in the Middle East are religiously inspired. The chances are that your family has been directly affected by one or both of these. Either way, everyone in that country is affected by them because of the effect they have on your elections, laws, taxes, television shows and, well, a million other things. If you've ever gone through customs, if you've ever heard of the Patriot Act, if you've ever disagreed with WBC, if you've ever seen a televangelist show or seen a campaign ad feature Romney or Santorum then you have been affected by religion.

Ridiculous beliefs lead to ridiculous acts. Acts which are often harmful. Even moderate religious people are problematic because they form a society in which extremists can exist. The fact of the matter is that, one way or another, you and me cannot peacefully coexist with people who think their god is going to send us to a place of eternal punishment simply because we disagree with them about what constitutes proper justification.

If someone wants to feel insulted because I point out that their views are ridiculous then they can go ahead and feel insulted. It doesn't change the fact that their beliefs are ridiculous and deserving of ridicule. People are entitled to their own opinions but they are not entitled to their own facts.

Many Christians believe that evolution is a lie and many Christians disparage the term 'theory'. To say 'evolution is just a theory' as if that doesn't also mean it is a fact is equivalent to saying 'gravity is just a theory' as if that doesn't also mean it is a fact. They reject the explanations of science while embracing all it does for them. This is not only ludicrous but hypocritical.

You may choose to be someone's friend even if you disagree on some fact or other and that's fine but how far can you push it? I imagine a friendship can easily survive differences over statements like "Justin Bieber is a good singer" or "Peanut Butter is the best sandwich topping". What about "Everyone should be vegetarian" or "Monkeys don't brush their teeth so I don't need to either"? What about "If you don't recycle then you hate the planet" or "The world will never run out of oil"? What about "All non-Muslims worship the devil" or "Abortion is murder"? What about "People who eat beans should be stoned to death" or "It's okay to kill slaves but only on Wednesdays"? What about "You voted for Obama? Don't you know he's an evil socialist? Why do you hate America!?" or "The world is flat and it's going to end on the first of April"?

You have to draw the line somewhere because at some point it's going to be your life on the line and you're going to have to care whether you like it or not.
