He doesn't understand what tolerant means. Just because we disagree with you Bill ( and yes even question your patriotism as is our right) doesn't mean we're intolerant. Even ad hom attcks are not intolerance. (Although the left is 100X as likely to that as are conservatives)
Intolerance is when you use speech codes to stifle free expression whne you disagree with it. I don't see conservatives doing that, but I see liberals doing that all the time on college campuses.
