Good idea. Anyways, I'm kind of happy there are people out there with such awful grammar. Grammar, like many things, can tell you a lot about a person. If they have awful grammar such as
then I know I'll probably not get along with them, and they are most likely age 12 or under. It's not universally correct, and I still give that person a chance, but it's a warning sign.
It's not wrong to listen to these signs. Some people call it 'judging someone' and would say it is wrong, but it's just your subconcious naturally warning you, 'Hey this person is a dickbag, you won't get along with him or her,' so when that person acts like a dickbag to you, you don't flip out and lose your shit on them back.
It's the same thing as if a stranger seems creepy you're probably going to be more cautious around that person, so when they try to stab you, you don't let yourself be stabbed.
