Again I think that's too narrow of advice to give. What is suitably drunk to prevent consent from being given? Where is the determining factor, and do you actually expect potentially inebriation, horny adolescents to be able to ascertain it?

Affirmative consent is a LOT harder to unintentionally give. It's easy to just mumble out an "mhm" to get the situations over with, but it takes thought and consideration to actually say words, "yes, I want you to -specific act-. Advising someone to always seek affirmative consent if they're unclear is MUCH more actionable.
