Why does it seem like the first reaction for an offensive question is anger?

I’m trying to understand better so that I can better communicate.

I realize that my views are offensive to many (as seen in my last question).

I have strong view points against a certain lifestyle. It’s not because I hate people who live this lifestyle, but because I am afraid for thier souls. This fear is based on my understanding of my religion.

It feels difficult for me to reason with a group of people who seem to shoot first and ask questions later. I want to know why does it seem this way. I want to learn how I can communicate my opposing point of view and have a reasoned conversation with a group of people who don’t like my point of view.

Also, I want to learn how to work through my point of view so that I don’t seem so offensive to others.
