Unfriend them if what they are posting makes you so upset.
I have one friend posting really nasty meme’s about Trump supporters being ignorant and uneducated etc. I ignored them for a long time ...I finally had enough of her liberal self-righteousness.
Sent her a private response and then promptly unfriended.
The sad thing is...they are all like this. From Hillary’s ‘deplorables’ comment to psychobabble like what is posted above. They hear and read this stuff and absorb it like sponges and for the life of me I cannot figure out why? Where is their common sense, critical thinking, etc. and it isn’t just the kids. This is mass group think and it is frightening as it never ends well.
I unfriended family (cousin) for posting garbage about Trump.
That's it in a nut shell.
