It's good to know that ElCid1970's reference to Fundamentalist Protestants as backwoods Biblethumping snake-handling goobers back in post #48 wasn't "making it personal."
On "open" Religion Forum threads posters may condemn deities, beliefs, religious authorities, practices, groups of believers, etc.
Posters who are offended by that town square type of debate should ignore "open" RF threads altogether and instead post to RF threads labeled "ecumenical" "caucus" "prayer" or "devotional."
That said, ad hominems say more about the poster than the object. I often remind RF posters that people do not use spit wads unless they run out of ammunition.
Ad hominems are also Logical Fallacies. The one of the receiving end would be justified in declaring a "win" on that basis and walking away from the debate.
