Remember that there is no paradox of tolerance if you treat it as a social contract instead of a moral issue: Those who do not abide by it are not protected by it.
This assumes there is some clearly defined line of what is intolerance that everyone agrees on. For a while at the company I worked at, just being a white male was considered "intolerant", so they fired many of them. The irony was not lost on the employees. It was a very oppressive environment and I'm glad it recovered. It's a famous company that aired some of this dirty laundry publically so you might be able to guess who it is.
Some people are black and white bigots like this comic, but people are stupid binary thinkers and call people out as intolerant who are not overtly bigoted or bigoted at all, but are of the wrong identity or associate with the wrong groups.
