Yes yes, language changes over time. I’ve heard that mantra for decades and I know it. That doesn’t mean there aren’t language changes that aren’t grating when they become fashionable (and hopefully temporary).
For me, “morals” being used as a crude catch-all application of “morality,” “ethics,” “integrity” or related concepts bothers me. Sentence example: “Maybe if society had morals there wouldn’t be so many minorities in prison.” 
An even more annoying otherwise-fluent-speaker modification I see is when “conscious” is used to mean “consciousness” and “conscience” interchangeably. Sentence example: “Single mothers on welfare that steal baby formula have no conscious.” It sounds like they’re saying the shoplifter is not mentally aware of their own actions, not that they’re lacking sufficient “morals” to let their baby starve for the sake of Rules-Based Order™.
There’s others, but those two come up enough recently, with sufficient newness, for me to bring them up here. Some old classic language quirks are so established and entrenched that even though I hate them, bringing them up would likely invite some hatemail and maybe some mystery alt accounts also sending hatemail after that. You know, because they “could care less(sic)” about what I think. 
I really hate the misuse of the word “pretentious.” A lot of people use it to mean something like “pompous” when it’s root is “pretense.” It’s only pretentious if someone is dissembling about how much they know about something. If someone actually knows as much about a subject as the appear to then it doesn’t matter how annoying they are, it’s still not pretentious.
And that’s my very specific pet peeve. And having this opinion is itself extremely annoying, but it’s still not pretentious goddamnit
A pretense doesn’t have to be in relation to knowledge that someone holds. A pretense could be someone acting as if they’re more dignified or esteemed than they are, which is practically the definition of pompous.
I believe everyone should have the right to dignity no matter who they are
As do I, but I’m using ‘more dignified’ in the sense of claiming to have a higher social status.
A bit pretentious eh?
Fun fact, pretentious and pretense are separated by more than 300 years.
I dance that line a fair bit and while I usually mean the correct version, the one involving pretense and implications of some bigger grander something that isn’t actually there, I may have annoyed you in the past by being too fast and loose with how I used it in the past. Sorry!
If you have, I’ve already forgotten and forgiven you
