It’s not apostasy (abandonment of one’s religion) or treachery (betrayal of one’s country or cause); it’s probably just a change in strategy and tactics.

But I distrust crusaders and activists who blithely change the names and banners of the cause they champion when the facts won’t suit them and they cannot win the argument. I dumped population management when its advocates started to change the terms -- from population control, to family planning, to planned parenthood to reproductive health.
