The problem with this approach is twofold; firstly it means that because of an implicit threat of force the majority have had their rights subordinated to the preferences of a minority. Regardless of the context of how this happens, this kind of precedent is always the first step on the road to tyranny. Secondly it is a recipe for social stagnation; if the state acts to prevent anyone from encountering views that they disagree with or might find disturbing then their view will never change and the state will find itself forever trapped in a paradigm of conflict and stagnation.
