Worse than “OOP is the one true way” is “OOP is the one true way and Java’s style of OOP is the one true OOP”. I’ve heard of a CS curriculum that starts by teaching Scheme and ends with a segment on “OK, now you know how to program in Scheme, here is how to do it in Java”. I don’t know if that can fit in one high-school class, though.
