How far Should Tolerance go?

What are the limits of tolerance in constitutional or liberal democracies today? This is a crucial question, for if there were no limits to tolerance, it would ultimately destroy itself by accepting the intolerable. The concept of tolerance has to be assessed from a political point of view, thus questioning to what extent its potential achievement does not suppose any moral mutation in humanity. For instance, if people were all already `virtuous’ according to a commonly held moral framework, there would be simply no need to speak of tolerance. Conversely, if it were the case that people could be made `virtuous’, then tolerance would be the matter of an improbable utopia. Ultimately, we need to consider how tolerance can be conceptualised in a way that is relevant to people and their societies as they actually are. In a time when a growing amount of political demands touches on themes of cultural identity and rights, and while we witness a mounting wave of religious fundamentalism, what should democracies accept and what should they refuse?
