Words such as "false" "wrong" "error" do not attribute motive and are therefore not "making it personal."
Discuss the issues all you want, but do not make it personal.
I must admit that one has to work pretty hard to extrapolate the above comment into a personal attack or an accusation of lying or to differentiate it from the categorical ad hominems thrown at Catholics, Rome, Papists, and RCs on a daily basis. Like playoff hockey you ought to just let this play out.
Peace be with you.
