I read in many different places on the Internet and it never seems to fail that the most intolerant people are the ones who claim to have the most tolerance for differences. They may accept this that or the other, but they will jump on you in a second if you dare disagree with them.
This shows me that they are just as intolerant as any they oppose, perhaps even more so, since deviating from their self-proclaimed tolerant line is sufficient justification in their own minds for them to call you any sort of name and supposedly completely ignore you.
Most of those who supposedly hold intolerant views mostly just want to be left alone. Why are the intolerant compelled to shove into their lives?
