Not quite correct. If you have left the Catholic Church for another then you have indicated a preference. You have placed the Catholic Church and its teachings on salvation, Scripture etc., below your own personal interpretations, not on a par.
Spin it any way you want but at the heart of that decision is pride.
Does Peter and Paul say we must not say anything to those that preach a false gospel?
In the case of the Catholic Church, you'd be better served by taking the "Gamaliel option", as described in Acts. The Sanhedrin was debating what to do about the preaching of the apostles and Gamaliel told them (and I'm paraphrasing here); don't mess with the apostles. If they're not doing God's work it will all come to nothing. If, on the other hand, it is God's work that they're doing, you'll end up fighting a battle you can't win.
Pride likewise convinces people to believe that they're somehow unique in salvation history in being the only ones to ever have taken up cudgels againts the Catholic Church. It's all been tried before to no lasting effect. From Nero and Diocletian to Calvin and Jack Chick.
Learn a lesson from history. The Church is Divine.
