No, your example is understandable and one with which I agree. The article I saw however broad-brushed with every instance. A good friend of mine went from Sherri to Sammi (to be fair she isn't transgender) and it took me a bit to make the change. Bruce Jenner may be Caitlyn but if we call her "Bruce" on occasion, because for 50-something years she was Bruce, we shouldn't take a beating over an honest mistake. That's the problem I have with the concept because some people are looking for reasons to be butthurt over every little slip. I have a high-pitched, nasally voice and was called "ma'am quite a bit over the phone. So what? Yet I know people who lose their shit when it happens. The person on the other end hears a high-pitched voice and they make the assumption. I don't care and it hasn't happened in years. If it happened tomorrow? So what?
Part of this rant is within the context of transgender people but to me it is symptomatic of a larger problem in our society today. Practically everyone is supposed to be personally offended over everything, no matter how small. We are creating a society of victims.
