I think “graduating high school” is a regional colloquialism. The grammarian in me shudders a little, but I learned from my dear former DIL that a number of constructions that sound wrong to the American ear are correct in British English. She assiduously learned them as part of her transition to living in the US.
Posts that begin with some version of “I waited until the last second on a holiday weekend to submit (x) but (y) prevented me and I can’t reach anyone at the help desk. Am I screwed?” are annoying.
Also annoying are posts from upper income people who will pay for anywhere their high stats kid wants to go that lament that they are somehow at a disadvantage. So many families are struggling to finance an education and you’re worried your kid may have to settle for a top 20 instead of an Ivy?
The posts from kids who assume they have the power to negotiate financial aid packages with colleges (across differences of tens of thousands of dollars) are just perplexing. Where are they getting these ideas?
Fine, but these kids are not British. In the least.
Yeah, but. Annoys me less than “Florid-er.”
“Someone told me that their friend’s brother’s cousin successfully negotiated with Yale.”
It might be technically incorrect, but it’s a common enough variant in my region, at least, that it doesn’t seem atypical to be used here. After all, language does change over time.
^Exactly. There are oldsters that say you can’t say someone graduated. They WERE GRADUATED from X school. But we don’t normally use that construction any more. Language evolves.
(Edited because the first “E” above was inadvertently typed lower case, and don’t want to re-open that can of worms! 
).
Having lived in three different US regions and two countries outside the US, interacting frequently with people from all over the world, I’ve heard “graduate HS” often enough (from US and non-US people) that I’m quite sure it’s a losing battle to insist upon “graduate FROM HS”.
A losing battle it may be, but that doesn’t mean it isn’t worth fighting. 
I’ll support your fight if you throw in “there’s,” when they mean “there are.” L-)
Sociolinguist and dialectologist here: The constructions ‘X graduated from Y’ and ‘X graduated Y’ are both correct, they’re just generally used by people from different regions. Claiming that only one or the other is or can be correct isn’t standing up for correct grammar, it’s an admission that you aren’t familiar with a wide range of standardized forms of English. There’s no shame in that, but you might not want to make blanket statements about certain linguistic forms being “incorrect” without doing some research on it first.
The ones where someone focuses on a hot button issue that is merely a detail in a post (that is not the point of the post) to start one of many never ending debates.
^^Oooh, me, that one was DEFINITELY me >:)
Piffle.
All sorts of abominations creep into “standardized” forms of English.
B-)

19 notifications on a thread I’ve bookmarked… only to come and find an argument over grammar.
This is a discussion, not an argument.
So undo the bookmark. Or continue to be annoyed.
@whitespace, Doesn’t that make this your current “most annoying thread”?
Spam thread with spam link…that here posters LIKED!
Okay, it wasn’t annoyed… more like mildly amused.
But I usually find some interesting stories or things to avoid here (I may be guilty of “graduating HS”) and was sad that I missed that discussion.
@austinmshauri Funny, didn’t think of that. But no, there are many much more annoying threads out there…
