First Amendment

I am so tired of hearing how the first amendment says that cross can not be displayed, how prayer isn't allowed, or how religious groups can't use school facilities. In case you are a modern liberal and haven't actually read the First Amendment it says the following about religion:

"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof;"

I think that the key point is "Or Prohibit the Free Exercise thereof". To me that would mean that I can exercise my religion and that the government doesn't have the right to tell me that I can't. So if they say I can't pray somewhere, I think that would go against the 1st Amendment not vice versa.

But as usual liberals, activist judges and atheist groups don't actually let the facts get in the way!
