See, my understanding of trigger warnings is more to prepare and forewarn students of difficult discussions. Like- "we're going to be talking about rape and its psychological effects tomorrow." Not- "WARNING- this textbook uses the word 'violate' when discussing DBs."
The first example seems like an obvious common courtesy, the second seems pointless. I say pointless because some words are used in everyday life in normal ways that may be "triggering", but that's entirely different from an in-depth discussion of a sensitive topic that's triggering. But that's obviously just my opinion, I'm sure many disagree and that's why this is such a hot button issue right now.
