Ladislaus wrote a wise post above -- referring to the post TWO posts up. (not his first wise post, and probably not his last).
I would like to say something similar: that "Trads are mean" can easily be an excuse. The fact is, your average old-school SSPX priest (some still in the SSPX, others now in the Resistance) isn't going to let you get away with much. He's going to be a damper on your "fun" -- more specifically, on your sins.
Of course no one is going to say, "I left the Catholic Church because I wanted to embrace the vice of self-abuse." I did know one apostate who was very honest and said "Catholicism was too hard." He was raised Trad, at least from age 11. He was raised by his grandparents, and never meet his dad. But he was brutally honest sometimes -- even to the point of rudeness. He also told a protestant friend that Luther's path was B.S. -- too easy. Like most apostates, he embraced NOTHING after he left the True Faith. But perhaps that honesty will come around to save him someday.
But to return to the modus operandi of apostates --
So they will come up with some polite, socially acceptable excuse why they're leaving the Church. There's an old proverb: it is easy to find a stick to beat a dog. When you decide to turn against a man, or an organization, you can ALWAYS find something to complain about, if you really want to. Heck, even if an organization were perfection itself in its ideals, goals, principles -- if it has HUMAN BEINGS IN IT you'll have no problem finding flaws "in the organization".
