Second, I imagine that some of you Roman Catholics think fondly about the good old days, before Martin Luther, when you could deal decisively with heretics such as these by burning them a the stake.That's pretty weak, a drive-by slander, suitably imprecise so as to apply to everyone, wrapped in a nice candy-coated shell.
Nope, it was a little humor, but my ex-M-i-L would have been happy to do it to me, being the fine, upstanding Roman Catholic she always reminded me that she was.
You might want to consider letting your skin get a bit thicker...unless, of course, you enjoy balancing that chip on your shoulder.
