Er, I most certainly, most definitely and most categorically did not say that 'Freser thinks sinlessness the only pre-condition for not exercising the death penalty'; these are your words, not mine (and not even Freser's).  Scroll back and read my post again, carefully this time. I used the word 'sinlessness' in reference to Jesus alone.

If you're accustomed to read the Gospel as poorly as this, then no wonder you put it down with such extreme notions as supporting the death penalty!

As for giving dissidents a hearing, why... if they speak l*es to truth? Would you, for the same reason, give Satan a hearing? He, too, is a bit of a 'dissident'. (Or so I've heard.)
