Tolerating intolerance

Robert Scoble made a comment today about dreaming "Of a tomorrow where political correctness is seen as a nicer way to live than spouting off any damn thing that comes to your mind (especially if those things include hate or intolerance)."

The thing I am most intolerant of is intolerance. I recoil from right wing conservatives' inclination to project their own dysfunctional nastiness onto others. However when it comes down to micro decisions about who we friend, or more challengingly unfriend, on Facebook this gets hard.

I don't want to end up in an echo chamber of people who agree with me. Having my views challenged and changed is part of why I love social media.

But nor do I want to be associated with people who I see as spreading attitudes that I think are hurtful to individuals or damaging to the fabric of society.

Where, and how, do we draw the line?
