Was it "liberals" who imposed desegregation on restaurant owners and were they wrong?  Should we still have segregation by race?  Why not still allow job ads that say "Catholics need not apply"?  Or, how about using national origin as a criteria for determining who will be allowed to immigrate to this country?  At one time all of this was allowable.  Was it "liberals" who forced all these changes?  That is what you are suggesting.
