i have a question about christianity and the law. i ask this question in R&S first and now i would like to get?

There are no laws in the US that "target" any religion. However, there are laws that, by their operation, will affect a particular religion more than others. In your example, not all Christians are necessarily against birth control, and not all people who are against birth control are Christians. The law doesn't "specifically target Christians", it targets birth control, which just happens to affect Christians more than other religions.

Your example isn't an example of a law targeting Christianity (and, in fact, the vast majority of Christians would not be ethically opposed to dispensing birth contol), but rather a law that requires everyone who is licensed as a pharmacist to dispense legal prescriptions.

I'm not aware of any laws targeting Christians and their beliefs. There are always some members of some religious groups who claim an exception to what the law requires because of their beliefs, but the laws are not aimed at those groups any more than any other group.

"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof..." - The U.S. Constitution

In no way is the birth control example targeted against any religion, that is targeted against pharmacists that refuse to give the lawfully guaranteed drugs that were prescribed by a licensed doctor, if a doctor signs a prescription, by law, the pharmacist MUST fill it, no matter what drug it is.

Your neighbor evidences the rather unattractive Persecution Complex that Christians have. If anyone disagrees with them, or if the government does not favor them, or if they are prevented from using the government as a tool for evangelism, they moan and complain, like they were being thrown to the lions.
