I become less and less interested in participating in social media as the years go by. I have contemplated quitting social media altogether, but it is the main source of contact with many of my relatives and former coworkers whom I would like to stay connected to. The downsides of social media do become more manageable when you actively manage what and who you see.
You don’t owe it anyone to “hear them out” on whatever their opinion is. If you can’t learn anything useful from someone who doesn’t share your views, morals, etc. it really isn’t worth following them, or allowing them to follow you. Unless your livelihood somehow depends on knowing what people who just want to be contrarian think, it’s not really worth your time or the loss of peace to keep them around.
It took me a while to realize this; I used to feel like I was going against some “man code” by pruning people who aggravated me from my social media feed. It has become pretty easy to remove the annoyances these days and has been therapeutic to some extent. If you’re not committed to leaving social media behind, but are finding it overwhelming, try removing the irritants from the friend list.
