"Tolerance" is a meaningless phrase.
Most of the examples of "intolerance" that you've mentioned in the OP are simply people disagreeing.
"Tolerance" doesn't mean that I have to agree with you, and the act of disagreeing, even being vocal with my disagreement, isn't being "intolerant".
Some great contributions guys and I am appreciating reading every one. Mojo that video was brilliant and whether or not we agree with everything the guy said, he has done his homework and offers something really substantive to provide food for thought.
But I have to disagree that 'tolerance' is a meaningless phrase. I am not speaking about disagreement or our voicing our disagreement. And I didn't GIVE any examples in the OP.
But here are some examples of intolerance of people for no other reason than they are who and what they are. These are by no means the ONLY examples:
A demand that Phil Robertson be fired from A&E due to his answer given to a GQ Magazine interviewer.
A demand that Chick-fil-a be boycotted for no other reason than the CEO supports traditional marriage.
A demand that Ellen Degeneres be dumped from J.C. Penney ads for no other reason that she is gay.
An effort to financially ruin a talk show host for characterizing Sandra Fluke as a 'slut'.
A demand to censure Trent Lott by accusing him of supporting segregation when he was extemporaneously praising a colleague on his 100th birthday.
A campaign to intimidate advertisers of Saturday Night Live to dump the show due to 'offensive' content.
Shouting down or refusing to allow somebody to speak on a college campus who was invited to do so.
Note that none of the targets of these campaigns were doing anything to anybody. They were not requiring contribution or participation by anybody. The targets were being targeted purely for being who and what they are.
It was not sufficient for the attacking organizations to urge their membership to register their disagreement with or boycott the 'offending' parties. They were out to physically and/or materially harm/punish those parties--actively hurt them--anyway they could. For no other reason than they expressed an opinion the attacking organization didn't like and/or are who they are.
Even if such attacking organizations were not politically motivated--they never go after their own who behave or say things badly--this is not something any freedom loving person should allow. Yes, we all are subject to certain protocols required of our immediate associations, employers, etc. But none of us should be afraid to be who and what we are out of fear that some unrelated angry mob, group, or organization will come after us and attempt to physically and/or materially punish us.
