I Think Arrogance Is Annoying

It's part and parcel of deflecting attention from their faulty argument to your moment of inattention. It's petty and mean-spirited. I love when, as so often happens, they make errors while criticizing mine.

Reminds me of what my mother would say when I came up with anything factual that contradicted her, even up into my middle years:

"Comb your hair!"

Or:

"Stand up straight!"

I agree that it's a way of trying to deflect attention away from the fact that you have just made a good point and they don't know how to respond to it. It's also very childish.

This has never happened to me, as I'm a stickler for spelling and grammar (with myself, though not with others).

What has happened to me is that someone has brought up something I did in the past that made them angry, that they had supposedly forgiven me for, and refused to answer the question that I was asking. Then, when I pointed out that the one had nothing to do with the other, they threatened to block me.

Some people just don't fight fair. I've learned to avoid such people, for the most part, though I still have an occasional run-in with some ignorant person.

It's an attempt at deflecting away from the logic behind your argument as well as an attempt to undermine your credibility in general.

When they do that I give them one or two chances to mend their tactic and then kick them in the knees :)

Remembering the rules for your-you're-yours-your's, it's-its, one's-ones-ones', it's-its, who's-whose, etc. can be as difficult to keep track of as the rules of trigonometry.

Its even more annoying when they randomly add...' im playing with my cock right now....'

Yes...really.....

It's a know it all thing which is pretty arrogant imo. I've seen even worse than that. People can be idiots and think spelling makes them smarter

but that bear by YOU'RE legs though...
i wanna see whats behind YOU'RE bear

It's bad form to do that.It's a way of trying to gain control.

Totally agree. I have been through it many a time.
