To the OP, judging by the rest of this thread, yes it's just you.
People can chose to deal with or not deal with a company for any reason they like, so if they feel that a company is too vocal on social issues and that's a reason not to use them then so be it. Of course given just about every company has been vocal on that particular issue good luck finding an airline which doesn't not have a position.
Moving onto the so called language document
I find this hangup on language an interesting one. On one hand you have groups which are angry if you dare use non-inclusive but historically acceptable language (eg chairMAN), but on the other hand will happily create their own "ist" terms which they say without a hint of irony or self awareness (eg mansplaining).
Personally I'm not too worried how I'm addressed (or any other language used) by a company representative, as long as it's done with respect. I'm not exactly a huge fan of "Mr", and I'd prefer people address me by my first name since I feel "Mr" creates a hierarchy where none exists, that said I'm not going to have a go at someone who does call me Mr Lastname.
Finally I'm having doubts on the authenticity of the document in question, just little clues such as stating "invasion" is acceptable language (and the posts by QF employees on social media stating they hadn't seen the document in question) is making me wonder if it was either a work in progress, or a complete fabrication. Because news organisations have never been known to publish lies and / or half truths.
