Depends on whether they can have a polite conversation.

I try to be polite, without making things personal. It’s always interesting to see whether or not the other person will resort to insults and personal abuse.

If they are respectful, I will almost always respond. If they immediately get childish and insultive I will likely ignore. If I notice they act that way in general to all they disagree with, I'll block.

If it’s just a disagreement and not an argument, we can discuss it if they really feel like it. If not, that’s okay because I don’t feel a need for agreement in order to interact with someone. I just don’t bother with it when it resorts to arguing nowadays.

Understanding and politely for a while, but when I see it's a lost case in every way, I'm just leaving.

Depends on how. If they can't do it like an adult, then they can just f**k off.

I/we agree to disagree...see ya!

Agree to disagree and leave quickly. 👋😊

Try to have a civil conversation with them to better understand their viewpoint and see if there are any aspects we can agree on, or if they can convince me I am wrong. But if all they can do is call me names, label me, and throw slogans at me, I will call them on it and disengage.

Calmly

I give over often because it's not important to me to be right or try to win. On some subjects I am relentless though

Block them !! 😑.. then unblock them to show them you aren’t playing around

With an attitude there is learning at the end, either I am right or have learnt my lesson.

I avoid them out of respect, unless they invade my bubble.

I disagree with this post

I tell them to go fuck themself

Throat punch

I don't waste my time.

Shit on top of their car

Same as I do with people who agree with me.
