I think these people go out of their way to be jerks. Not only are their actions disgusting, it embarrasses me that they call themselves Christians.
And you just won the prize for a most astute observation...”they call themselves Christians.”
Anyone can call themselves anything they want to, but that doesn’t make them one.
They obviously are not CHRISTians because if they were; they wouldn’t be doing what they are doing — which is spreading hate.
