"Bible thumpers" was among a few of the responses on this thread. Interesting label that says much. Does tolerance only apply to some and not to others?
Whoever told you that indiscriminate tolerance is the highest of values?
As far as political ideologies or philosophies are concerned, I know of none that explicitly elevate tolerance of ignorance to a virtue.
I'm not talking about IDIC, but about ideologies that actually exist and matter.
