I said

This breaks my heart, but your support of ICE leads me to think that we can’t be friends anymore. I am sorry.

He said

OK, unfriend me then. But if you do, you are narrow minded.

Then I said

ICE murdered Renée Good and Alex Pretti and drags American citizens out of their cars and uses kids as bait and violates the 4th Amendment on a daily basis. However narrow-minded I am, please consider the blind eye you have turned to this brutal reality.

Thanks for the good times. Goodbye and good luck.

And I unfriended him.

And I wonder how many more such exchanges have taken place.
