I know you don't mean this, but what you just said sounds like, anything must be tolerated if it is called a religion. But, this cannot be true.
The question then becomes, what cannot be considered a religion? I suggest, any philosophy or ideology which advocates the destruction of all other peoples and soceities is not a valid religion. I don't care if everyone who belongs to the religion does not believe it. We need to show them that is what it teaches, and tell them it will not be tolerated.
If tolerance is right, the one thing it cannot tolerate is intolerance, especially when it masquerades as a religion.
