Islam does not hate christianity

But that's the fallacy - that's not the definition of "Scotsman"; at any rate its certainly not the definition offered at the beginning of the argument. You commit the No True Scotsman fallacy when you redefine something mid-argument in response to a counterexample.That's why it's such a pernicious fallacy; you commit the fallacy of begging the question while using a fallacy of equivocation to conceal it. Ad-hoc redefinition of "Christian". "Christian" merely refers to those who assert that they follow the teachings of Christ. Whether or not their actions demonstrate that they do follow those teaching is quite irrelevant. They're still Christians if they claim to follow Christ.

Yes, exactly. And when you redefine "Scotsman" mid-argument, you're committing the fallacies of begging the question and equivocation; that's the "No true Scotsman" fallacy. Right again. The people we're talking about have chosen to be Christians; they've also chosen to do bad things. Oh, so it's deeds that get you into heaven? Not faith?I mean, that's really it, isn't it? If you're saying that you can't do bad things and be a Christian, how can anyone be a Christian? Aren't we all sinners? Don't we all do bad things?You're a sinner, of course - how can we expect to believe that you're a Christian?
