"No True Christian" fallacy

What the hell is it with Christians today? I've had one, Miles Militis, attack my appearance because he's a vile little Facebook bully with a severely objectionable personality, he also 'called me out' with the offer of meeting me in a gym's boxing ring (seriously, this is a Christian!?) then I ventured onto Twitter to find that @ImH0me, whom I have mentioned on my blog before, seemingly doesn't understand what the “No True Scotsman” fallacy is, or to what it applies, and also doesn't understand what “Leave me alone” means. Maybe it's the heat … or rampant stupidity.
