State tolerance is an offence, not a virtue

in this article the author makes a simple claim: in present days, several political leaders use the term tolerance to qualify their attitudes towards certain kind of people, practices and cultures. the question is simple: is the tolerant state allowed (morally and conceptually) to speak about tolerance? the thesis defended by the author is that the modern liberal state cannot (because of conceptual reasons) and should not (because of moral reasons) talk about tolerance.
