Perhaps, but my comment was merely an observation, nothing more meant by it.
While neither of us can say authoritatively what exactly happened, there are plenty of written examples and eyewitness accounts of such happening that it's hard to deny that many of the faithful who were martyred were killed for either not recanting or not renouncing their faith. We can quibble over statistics, but to blanket deny that anyone would ever do that is to ignore multitudes of eyewitness and first hand accounts of people being martyred.
I'm not talking about people fighting a revolution. I'm talking about people who were peaceful and not a threat to anyone being martyred for no other reason than being Christian.
Certainly it's happened to adherents of other religions. I don't deny that. But I think it's a topic worth acknowledging that Christians have faced persecution for 2000 years simply because of their faith.
And sure, a lot that's happened over that period of time has been a mix of politics and religion, but that doesn't invalidate the idea that people have been killed on the basis of faith alone for centuries.
