“Treat people as equally valuable, but treat ideas as if some are better than others, because they are. Some ideas are true, some are false. Some are brilliant, others are dangerous. And some are just plain silly. Real tolerance is about how we treat people, not ideas. Classic tolerance requires that every person be free to express his ideas without fear of abuse or reprisal, not that all views have equal validity, merit, or truth.” – Greg Koukl
The claim that “all views are equally valid” is a logical contradiction, just as the belief that all ideas must be accepted and unchallenged is intellectually empty. Nor does challenging an idea make you “bigoted, disrespectful, ignorant…[or] intolerant.”
Tolerance is easy, and so is thinking — you just have to do it.
