Publicly debating doctrine is not "shooting the wounded".
Debating doctrine is... debating doctrine.
"Shooting the wounded" would refer to being cruel to someone who has committed sin, or fallen in the faith, and who is repentant, and now needs support and forgiveness... and INSTEAD of forgiving and helping them, we turn on them.
This has nothing to do with debating doctrine.
Whenever someone wants to publicly proclaim HORRIBLE DOCTRINES,
and someone else stands up and corrects their doctrine,
they immediately want to "play the victim",
and accuse you of HARMING them.
This is nonsense.
If you're going to preach a doctrine, then be able to back it up.
