If you think that tolerance of all values and value systems is good, are you not then “imposing your values,” your value system, which includes the value of toleration, on other people or other cultures, not all of whom agree that toleration is a value? Many traditional cultures see toleration as a weakness, as a disvalue. So for you to say that everyone ought to be tolerant is for you to say that your value system, with tolerance, is really better than others, without tolerance. Isn’t that “imposing your values” on others? – Peter Kreeft
