In the following writing, I intend to show what appears to be a serious flaw in just one frequent articulation of what some in the past have meant by the word "tolerance". I've not seen it used egregiously in these forums, but modern (rather postmodern) construals of the term appear regularly in popular rejoinders to more conservative initiatives in social theory.
Consider the following proposals:
1) It is better to impose a moral view upon society even if it is done so involuntarily against some of its members who may disagree with the view in question.
To counter an alternative:
2) It is better to not impose a moral view upon others involuntarily precisely because they may not hold to that view as true.
I argue that in any case, proposition (1) must win out. If there should arise a disagreement between proponents of each view, those of the second should give in to the first, since it is not within their code of ethics to impose their moral view involuntarily against even their opponents.
