If you claim to be 'tolerant', but do not tolerate those who aren't, you are not really tolerant. Period. What a truly tolerant person should do with those who aren't, is to find ways to persuade them to change their ways. It is not impossible. Civil rights movements in 1960s or suffrage movement achieved success not by scaring 'white racists' or 'male supremacists' into submission, but by persuading a sufficient number of them that segregation or discrimination based on sex is bad.
