"Let's be careful when we start comparing American to European tolerance because there isn't necessarily a lot of European tolerance"

This quote by Montel Williams is an alerting to be careful when comparing American and European tolerance. He is recommending that there is not always a great deal of European tolerance, which we need to beware when making such contrasts. This might be translated as a caution versus making sweeping generalizations about the level of tolerance in Europe, as it is likely to vary from nation to nation. It might also be translated as a suggestion to be mindful of the differences between American and European cultures, and to be considerate of those distinctions. Eventually, this quote functions as a pointer to be mindful of our words and actions when going over the level of tolerance in different countries.
