"At its heart, [tolerance] is a philosophy and moral commitment to accepting the rights of others to believe or behave differently from ourselves without excluding or penalizing. Don’t expect champions of tolerance to 'tolerate' acts of exclusion or bigotry that represent the very opposite of the principle they hold so dear."This statement is self-refuting. If you can only be tolerant by accepting others who believe differently, then true tolerance cannot be intolerant of anyone - even those who are intolerant. Being intolerant of intolerance still makes you intolerant (which should then cause you to reject yourself).
The modern "tolerance" movement is not about tolerance at all (as shown by their intolerance). It is an alternative morality - one which rejects the Bible.
