I would! I never had a "face-to-face" confession to a priest. Not saying they would refuse to do so if you asked, just that it was NOT the usual way it was done. I believe that was really the gist of what was being discussed. This is yet another example of the hair-trigger reaction and rush to judgment of some RCs here who are ever ready to falsely accuse another Christian of lying - especially one who left the RC religion. You didn't. We know it.
I think the real reason face-to-face confessions are the path less chosen is due to the shame of sin. This is my view of it, not speaking for the Church, so if I err, forgive me. The ability to confess your worst sins to a man committed to serve the LORD Jesus Christ for all his days above all else, who will never betray your confession to his dying day, who is your witness before God and wants you to be saved, who believes in the Scriptural requirements for repentance and forgiveness, who in faith and by faith will pronounce you forgiven according to the Scriptures, is a beautiful grace extended to you.
You are correct in part about the example of a hair trigger reaction to met mom. She was ignorant of the opportunity and did not use the word "liar." She was wrong and only merited instructive correction. The Holy Spirit cannot be pleased with our pettiness. Where you were wrong was to label her a "Christian" and the other faith as the "RC religion." You should name both denominations, if at all, or label both Christian in this case.
