Mt 5:22
But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.

Your original statement asserted your right, in fact your duty, to save a brother or sister from a life threatening situation. So far so good. So you then decide to inform the brother or sister of the grave danger to his / her immortal soul that his / her lifestyle places them in. So at this point, the dialogue has been initiated by you. The other person, drinking his Starbuck's coffee had no idea that you were about to intervene. He does not know you and has no reason to be angry with you. So the exception to Mt 5:22 that you draw attention to above is not applicable in this case. The brother is not angry with you.You therefore, are bound by the verse. You are obliged not to say Raca, not to call him a fool, in short not to engage in any abusive language.

But instead, you feel free to use very abusive and de-humanising language by calling the brother or sister "queer" and worse. How do you reconcile this with the gospels?
