Conservapedia Humor:

Conservapedia has an entry for "Martyrs to the faith". (Their capitalization, not mine.) They define martyrs to the faith as, "the Protestants who were executed by Roman Catholics during the Reformation of the 16th century." They then go on to provide a very interesting list of examples, that includes:

• John Brown. executed in the late 17th Century for refusing to acknowledge the British Crown's authority over the Scottish church.
• Richard Cameron. A Scott who died in battle in the late 17th Century.
• Donald Cargill. Yet another of the Scottish Presbyterians who died in the 17th Century while rebelling against the religious authority of the Church of England.
• John Greenwood. A puritan, executed during the reign of (Protestant) Elizabeth I for refusing to conform to Anglican beliefs.
• Christopher Love. Puritan. Executed during the English Civil War.
• Felix Manz. Swiss Anabaptist executed for heresy by Protestants.
• John Penry. Puritan executed under Elizabeth I
• James Renwick. Yet another 17th Century Scottish Presbyterian.

I could go on, but I got bored. Let's just put it this way: more than 25% of the first 30 names on the list were either not executed by Roman Catholics, not executed in the 16th Century, or both. One of them actually died in battle, and the last time I looked "fighting back" wasn't exactly part of the traditional definition of "martyr".
