Is it ethical to ban people from the pledge of allegiance?:
I agree with you. If a person WANTS to say the Pledge before a meeting (game, class, etc) then they should be allowed to do so. No one is forcing others to join in and pledge -- they are perfectly within their rights to abstain. 

It really p*sses me off when people try to claim that just "hearing" the pledge violates their rights. Well, what about my right to assert myself and my allegiance to my country?? I would think that would trump anything else.
