Does this annoy you? (Inside)

Okay, maybe not to the extent of annoyance, but the fact that it’s becoming too common, tends to personally annoy the hell out of me.
I notice people tend to mistake ‘breath’ for ’breathe’, ‘you’re’ for ‘your’ or vice versa, and ‘to’ for ’too’. ‘It’s’ for ‘Its’.
I’m not saying I’ll kill them or anything, but there’s this powerful urge to correct them, because not only do younger people do that, it’s also common amongst older people as well.
And no, they’re not doing it with the intention of using an informal manner of typing, they genuinely confuse/don’t understand the difference between both.
How do you feel about common mistakes like that?
I’m not trying to be rude or anything, it’s just that people should refer back to the most basic rules of grammar.
You might think it’s none of my business, but oh what the hell.
