The first two look correct to me, while the last two seem problematic, more confused than false, because they seem to confuse revealed preference with believed preference. I can only struggle against the preferences I believe I have, which might not be my "real" preference. Certainly, my revealed preference will win, by definition :-)

But that's no reason to doubt that my struggle against particular preferences will fail, let alone that my preferences have enough agency to defend themselves. If it weren't for the word "protect," I might prefer the fourth to the third.
