Apostacy happens when someone says reject the faith or die. Like ancient Rome or modern ISIL. It is not dissent and it may not even be Protestantism, since these sects are still considered part of the Western Church. Nor is it having a position on the Filioque (sp?) that is at odds with that held by the Orthodox Church and the Archbishop of New Rome (a title that claims Petrine succession). So, quit throwing the word around unless you are willing to concede that by not being Orthodox, you are apostate by your own rules. And get better insults, Yours simply concede defeat.
