A friendly reminder regarding people who use the wrong language regarding minorities
If you're talking to someone who you haven't tried to correct in the past, try to keep in mind that their choice of language doesn't necessarily mean they're a bigot.
They might genuinely not be aware that they're using wrong/outdated language (this being especially true of older people). They might even be in the process of learning about how to be respectful and just haven't got to learning the proper terminology yet.
A couple weeks ago I had a Boomer coworker ask me why our manager and I (the only Millennials in the senior staff) put our pronouns in our automatic email signatures.
"Like, what is it for? What's the reasoning behind it?" she asked, clearly genuinely interested in understanding. So I explained to her that it isn't so much for our benefit as it is for the benefit of trans people. That it's meant to normalize not assuming people's genders while also serving as a signal to trans folks that we're allies and that our place of work is a safe space for them to be in.
"Ooooh, okay, that makes sense. That's a nice idea." my coworker replied. We discussed trans issues a bit more and she used the wrong terminology regarding trans people (using "he" in regard to trans women athletes), but it didn't come from a place of malice. She's in the process of learning and has demonstrated that she believes in inclusion (when she used the wrong terminology she was lamenting that it would probably take a while for trans women to be truly accepted into female sports teams).
