I discovered recently someone I know personally has unfriended and even blocked me on FB. We weren’t close friends but I can’t ever remember having a falling out of any sort. Granted, I didn’t even notice said person had unfriended me for quite some time. The only recollection I have is that he and I often had slightly different political views. We disagreed a few times but it was never mean or rude. He would get rather upset with anyone who didn’t agree with him. I’m left to assume he got mad because I disagreed on something and blocked me. Oh well. He was clearly missed. /sarcasm
This last week I noticed I’ve also been unfriended a few times by folks who didn’t agree with my views on current events. It seems to be a growing theme on social media. Basically, people don’t want debate, they only want supporting comments or views that reinforce their own. Then they get super upset or bent out of shape if someone disagrees with them. If you don’t want comments from people who might disagree, either don’t allow comments or don’t post it.
For myself, if you can’t handle debate then I’m sure we wouldn’t be friends in real life anyway. Successful discourse requires two way communication not just pontification of your own thoughts. I usually try to keep my discussions to the topic at hand without any personal attacks. I also try to refrain from name-calling and inflammatory comments. I say ‘try’ because even I lose my shit sometimes.
Anyway, I’m off topic a bit. If you friend someone you don’t really know on social media, you shouldn’t be overly surprised if they don’t always fall in line with your view of things. Barring said personal attacks mentioned above, you should try to converse and debate vs just writing them off and unfriending them. You, or they, might learn something. You also have the added benefit of developing a deeper understanding of your own belief. Teaching or explaining concepts to others forces you to better understand it for yourself.
