Jo,
You've opened a can of worms on this one as I'm sure the the list will continue to expand. I have to agree with the gender identity bs as it's getting way out of hand.
I also cannot stand when people use the word "like" after every few words but I'm guilty of doing it without even realizing it. That or I say fxck or fxckin after every few words.
As of late, I've heard the word "bet" as in "you betcha" and "facts" as in "I completely agree." The urban dictionary is full of useless but sometimes entertaining one word phrases.
And lastly, my biggest pet peeve is basic grammar. For example, when someone texts or emails the words there, their or they're incorrectly. Also included is your and you're, two, to and too followed up by then and than.
The fact that smart phones can autocorrect your spelling or that someone came out with an app that checks your grammar, just goes to show that most people are either lazy or inherently uneducated. Grammar schools are no longer teaching children how to write in cursive and we as a society are becoming dependent on digital signatures. It's basically the equivalent of a person that was never taught how to read or write being asked to "Make their mark," usually by signing with an "X." Just my 2 cents. Who hates this one??...lol
