In today's politically correct atmosphere, tolerance seems to be a very misunderstood word and concept. Webster defines it as, "sympathy or indulgence for beliefs or practices differing from or conflicting with one's own." Yet, today's liberal media and academia seem to label anyone with a differing opinion from theirs on many issues as intolerant.
Tolerance is the act of tolerating. It is not the act of approving, sanctioning, or endorsing. Those who preach tolerance the loudest often want dissenting opinions silenced, therefore they are the least tolerant of all. Tolerance by definition requires a diversity of opinions. Without a differing viewpoint, tolerance is impossible.
