I'm uncomfortable around the bi kids on my bus
Why are you uncomfortable around them?
I hate them and their weird lifestyle.
Even though they may have a different sexual orientation from you, they are still human just like you. They have feelings and emotions like anyone else and people should treat them the same way they themselves would want to be treated.
Why should I? It's not like they are in danger of getting beat up by homophobes.
Members of the LGBT community are actually commonly victims of hate crimes that target them for their sexual preference. Even though you aren't physically beating them up, treating them different because of their sexual orientation can make them feel ostracized and lonely and make school life difficult.
