I got called rude for not rolling my window down for Christians

I'm not trying to offend anyone but I find people who go door to door to preach to people regardless if they know their religious beliefs annoying as fuck. Because even if you tell them you aren't christian they don't fucking leave. However these same people if you went preach satanism which is a religion to them, they would call the cops on you. Anyway they take is a step further. All week these people have been standing at stop lights to go knock on the windows of stopped cars to preach to them. I find this so fucking rude. I'm at a stop light. I don't wanna hear you preach to me. First time I was nice. The second time this person did this I said "Listen. I'm Pagan." And they said "Well would you like to be saved?" What part of "I'm Pagan means I want to be saved?" I said "No. I am Pagan. I don't believe in what you believe in. Plz stop knocking on my car window." It happens a third time and they were like "Listen. God is reaching out because he wants me to save you from this devil religion blah blah blah." The 4th time I don't roll my window down. My mom said I was being rude. No rude is thinking it's appropriate to knock on people's windows at a stop light to preach to them. And then continuing after they told you to stop. I will not be rolling my window down for these people anymore.
