I'm not a Christian, but I think that quite a bit of what you say is simpley taking offense because you wish to do so.
If a person wearing a cross is offensive, that's your problem. If walking past a church is offensive, that's your problem. Likewise being offended by an advertisement or other such.
If you choose to attend a school where a nun teaches a college class, and are offended because she is religious, that is your problem. You can choose to be offended or not.
On the other hand, being required to swear on a Bible shows ignorance of the party requiring the swearing. I would simply tell them that they are asking me to swear an oath on a book that means nothing to me. With little meaning in the book, an oath on it means little as well.
I do despise displays of the ten commandments in court rooms. The inform anyone of any religion that they shall be judged based on the tenets of a single religion; in my case a religion that has killed many of my own faith as well as ancestors. Comforting, isn't it, to know that the same might hold themselves in judgment of me?
Falwell and his ilk are idiots and show Christianity to be what it is. Blaming the destruction of the WTC on homosexuals is astounding ignorance.
ID should not be taught in schools. It is a religious hypothesis that does not meet the tests required of a theory.
George Bush speaking his own faith is not a problem for me. If he imposes his religious beliefs on others, that is. Using his faith to demean another bothers me as well. His statement that Wicca shouldn't be permitted in the military was a problem as well.
Being accosted by Christians and told that my religion is somehow deficient bothers me. This happens fairly frequently. I don't mind, at times, discussing religion with such, but hearing someone yell, as I'm walking into a store, "Jesus is better", with somebodies finger pointing at my jewelry sort of stinks.
I'm all for religious tolerance. I don't mind churches, and I don't mind religious people. I don't mind nuns wearing their habits or priests in their collars. I don't mind people wearing religious jewelry. What I mind; what bothers me greatly is people who wish to impose their religion, or their religion's rules on a society which does not welcome them.
