You actually do, in this case. If using the terms "male" and "female" causes harm, the harm it causes is psychological. You can't really realize it from the outside. There is nothing to pre-empt here: These terms are already used to either they already cause harm or they won't start doing so. Which means there is no reason to effectively guess if they cause harm since you can actually ask someone who you think may be harmed. Solving a problem that doesn't actually exist is just a waste of time and resources. Moreover, it gives people the impression that "wokeness" in general is just pointless virtue signalling.
