I'm going to call out my friend on facebook
What do you need to call him out about?
He ignored me during a social gathering and that's really rude.
I'm sorry he was being really rude to you, but some matters should be dealt privately. It's not good to air your dirty laundry like that and cause even more drama and tension between your relationship. Just talk one-on-one and resolve things without embarrassing the both of you.
The person deserves to be called out even if he is my friend. It's not like he is going to see my post.
I think that everyone is going to see that if you post it. It is not okay to embarrass a friend like that. I really think that these matters are best solved in private.
