Whilst there is a decidedly different vibe here, I do think you have to ask yourself if you are taking people's advice the wrong way. Are they being insulting to YOU or are they being insulting to outdated, outmoded, broken methods you've been learning from bad sources.
Online there's a lot of just plain web rot. Broken garbage methodology that when people who've been doing this for anything length of time see it being done, are going to knee-jerk into "WHY the *** is this still even being taught?!?" --- then it's like "oh, nube predating scam artist BS like W3Schools, that's why!"
From halfwit shortcuts like jquery, to bloated broken garbage like bootcrap that defeats the entire point of HTML and why CSS is separate from it, to major accessibility failings so common to a lack of many tutorials even teaching you what the HTML tags ACTUALLY MEAN, there's a LOT that we as a whole NEED to be insulting about to drive beginners away from them. Blowing smoke up people's backsides and patting them on the back with soothing-syrup words is NOT helping!
If someone is using insulting language is it directed AT YOU. Are they ACTUALLY trying to help? Are they explaining WHY they are saying the things they are saying?
... and that's my problem with Stack Overflow and many other forums, people will do one-liner drive-by posts like a bunch of mentally enfeebled half-tweets without explaining WHY.
INTENT, that's what you need to look for! The REALLY GOOD programmers tend to be brusque, frank, and not take the time to sugar coat things. The language used may be colourful, but that is because they are trying to HELP. You should be more concerned with the turds who are using soft-language to slap the rose coloured glasses on your head, leading you down the garden path to failure, where everyone is singing kumbaya around the drum circle where the unicorn is farting rainbows -- since universally such folks (see "sitepoint") are looking for a new batch of suckups and sycophants to sell something (like their latest reprint of decade out of date books) to you. Hence why people who DARE to criticize anything -- regardless of the language used -- aren't welcome there.
Look at WHAT is being said, not the language.
That said, one of the biggest problems I have across various sites are the people who do things like say "google it" -- as if you haven't tried. If you're a beginner you might not even know the right terminology to type into a search engine to get a result! Likewise you'll often get the clowns who will say something vague in one sentence and then somehow expect everyone else to be mind readers and have some idea what they meant. I haven't seen either of those here yet.
That and this place seems to have far less TLDR mouth-breathers screaming "aah, wall of text!?!" like a bunch of illiterate five-year-olds. JOE FORBID you try to explain anything or hold an adult conversation.
But to be fair, I seem to have entirely different definitions of "respect" and "insulting" compared to most people online. You'd almost think I was from New England. Where plattitudes and fake smiles at best garner distrust, at worst a fist in the face. Where sardonic wit and the backhanded compliment is as common as your morning Dunkin's run. Where "Yah cahnt geht theyah frum heeyah" isn't a catchphrase, it's a way of life.
Respect must be earned, not automatically handed out like participation trophies.
--- slams full coffee across your windshield -- Go back to Starbucks!
To that end, do NOT take offense to anything I tell you as my INTENT is to help. If anything I say is colourful or can be misconstrued as insulting just remember I'm trying to emphasize how what you have learned elsewhere is broken, and I'm TRYING to show you better ways of doing things.
... and that's the REAL difference IMHO you need to look for. ARE THEY TRYING TO HELP? Yes or No? If no, THEN go ahead and feel insulted. If yes, then the problem is you, not them.
If I'm curt with you it's because time is a factor. I think fast, I talk fast and I need you guys to act fast if you wanna get out of this. So, pretty please... with sugar on top. Clean the ****ing car.
