I'm going to humbly suggest that by your standard nearly 100% of Christians are apostates. 
By your logic (and I'm being pretty generous, I think, to call it that), self-identification as a Christian has no meaning because only "god" can determine if one is "truly" a Christian. The only problem is that you have no proof of "god" either so how can you prove what/if a Christian actually is or how he or she might be different from any other person who does not self-identify as Christian? I think it's nice though that we both seem to agree that there's quite a lot of hypocrisy where "Christians" are concerned.
