Public Displays of Affection in schools

This is for all the schools across America. I am a student a Jim C. Bailey middle and I am pretty sure most or all of the school in the united states clearly forbid public displays of affection if the schools dont let us then why should the united states even consider letting gays marry? I think it is completly wronge! I think we have a right to express and show that this person is ours and just as long as we don't take it to far as in making out in the hall way, at my school we are not even allowed to give each other a hug if a teacher see's we are automaticly written up for "making out" in the hallway. Some couples live very far away from each other it's not like on saturday they can walk over to there boyfriend/girlfriends house. Some people think it's innapropriet to be able to do that but there are also many students who think it is wronge, we should be able to show and express our feelings (real or not) !!!
