Fine - but it isn't a matter of rejecting or accepting; but rather of understanding. And if someone isn't "qualified" to reject a certain architectural pattern... then they probably won't be very good at implementing it either.

So on balance I'd rather be in an environment where people are allowed to "reject" what they don't fully understand yet -- rather than (pretend to) go along with it (on the basis of some article they vaguely read about it, or "because X said so.")
