And you think the exception somehow counters an argument that contains the word "usually"?
It counters this argument you made which I responded to, I'll quote it again:
I was just pointing out a distinction between the way SNW did it and the way Trek has historically done it,
Your argument is bulshit, there is no distinction as Trek has in fact "historically" done exactly this, all the way to the very beginning.
As for "usually", well duh, "usually" there aren't any Romulans in a given episode, doesn't mean they're not a part of Star Trek.
