I wouldn't say uncomfortable, but I do SUGGEST the change. Typo's happen all the time, we're humans -- not Gods. I was raised on the idea that when you see something wrong, you tell the person what's wrong so they can fix it.
Sadly these days such activities seems to be magically transformed into some form of personal attack -- you screwed up; OWN that. I screw up all the time, I'm fine with that. Getting your knickers in a twist because someone else found a typo, or bad practices, or outright mistakes is infantile... and indicative of a much deeper rooted societal problem that seems to be taking over.
... as now you can't even say anything negative; or you get the half-witted limp-wristed "It's not what you said, it's how you said it" BS; a lame excuse to just sleaze by on as little effort as possible and/or open the door to every two-bit scam artist and snake oil peddler.
But you know how it is, *Sex and violence are fine so long as nobody uses any naughty words." -- what South Park made fun of fringe whackjobs for twenty years ago is now the societal norm. You'd almost think we were conditioning people for generations to be herded about by outright lies -- creationism, science denial, cramming jade eggs in the holiest of hoiles, anti-vax, "organic foods" -- with mouth-breathers yumming up that type of manure as if it were chocolate soft-serve, is it any wonder so many hucksters and carnival barkers are able to take advantage of people on the IT side of things?
... and it all starts with the "wah wah, somebodies pointed out a mistake" mentality and endless apologism.
You see a mistake, POINT IT OUT. Otherwise they'll never learn or get better. YOU make a mistake and someone points it out, it's NOT a personal attack and if you don't know what's being said, LEARN!
I swear, with this attitude of slapping the rose coloured glasses on everyone's heads, whispering soothing-syrup platitudes in their ears whilst leading them down the path to failure to sing Kumbaya around the drum circle with the rainbow farting unicorn... well, it's hardly a shock the house of cards we call the Internet smells like shantytown sausages!
