Would you remove Facebook friends who ignore you? I have a few who do this. It bothers me that they post messages to mutual friends but completely ignore me.
i don't care if people remove me. They weren't important anyway.
Remove them. They might not even notice since they don't receive a notification when they are unfriended. I have FB account so I can keep up with former coworkers and family that doesn't live near me.
If someone's views are really slanted where tolerance is an issue, I just unfriend them. I don't need to see all that crap in my newsfeed. If they don't add something positive to my life - only negative - BAM! They are gone. Life is too short!!!
