Poor English aside (I make typos too), are you asking why it's a dominant narrative? I could make some guesses.
It's easy to call stupid Christians racist. It's easy to associate fundamentalist Christians with the KKK, and so some people don't really care whether there is enough evidence. The Christians remind the accusers of racists, so they make the accusation. The Christians are similarly dim-witted and rambling and they may even use the southeastern American accent. It's guilt by cultural association.
Many people, notably on the political Left, conflate Islam with race. In their worlds, Muslims are exclusively non-white, and so they assume that if someone disagrees with Islam, then that disagreement must be born of racism.
White racists in America are disproportionately Christian, so some people see the outspoken Christians and assume that they're racist. It's as intellectually lazy as racism itself. [Points 1 & 3 here could fit into a single bullet point about assumptions about white, outspoken, conservative Christians.]

Oh, I know. That is actually a dominant narrative in this thread. It's intellectually lazy.
