People keep telling me that I should respect the beliefs of others. That sounds entirely reasonable, at least until you think about it. The problem is in knowing where to draw the line. I can understand why, for example, Presbyterians should respect the beliefs of Methodists. They’re practically the same thing.
But what about those Heaven’s Gate guys who believed they should kill themselves so their souls could follow a comet? Am I obligated to respect those beliefs too? How about the people who give away all of their possessions because they have determined the exact date that the world will end? Do I respect their opinions up to the predicted end-time and then, after it passes, keep on respecting their opinion while they are begging the neighbors to give back their crap?
He's absolutely right. At some point, common sense must prevail, and failing that one would hope that a sense of self-preservation would prevail.
