Freedom of religion

The first amendment to me means that we should have complete freedom of religion, with no one telling us what we can or can't do. I think that the government shouldn't make the schools not mention anything religiously. The school isn't allowed to pledge allegiance to the flag now, and i think that it's dumb, and unfair that we can't pledge allegiance to our flag. It's unfair because everyone has the freedom of religion and that means that we should be able to worship however we like where ever we want to. The banning of saying prayers over the announcements is going against our freedoms. The government even has religion incorporated in it. When we swear in the president his hand is on the bible. This shows that we have many flaws in our freedom of religion, and that restricting our rights is unfair.
