My youth pastor put a post about abortion on his Instagram that I disagree with. I feel I should argue my opinion with him.
What do you want to argue with the pastor about?
I want to discuss with him why he is so biased against certain topics
Even though he is a pastor, you are allowed to argue with him. It will make you able to understand each other better.
I just want to talk about how badly he is wrong.
It's okay for people to have different opinions. Maybe if you are able to express yours well, he will reconsider his own opinion.
