"Whether it comes to trying to teach people how to play their job, learn mechanics or what have you. This community a lot of the time just seems to have paper thin skin."

Agreed, but when it comes to giving advice it's better to lead them to a "discord" or website that can help. Unfortunately, we currently live in the age of disinformation and people believe all sorts of crazy stuff. So they are more inclined to only believe the "research" they do. So I guess it depends on how you chose your words to "Help" them. What I find that works best is to send them to "The balance" for example. A place where they can do their own research with a large group of people that can help.

If you are in a 4 man instance and try to give advice I can see how they could feel that they are being isolated and "Picked on". It's a tough situation to help people these days, so if you want to make the community better you have to put in more effort on the words you chose. The other option is to not say anything at all. The choice is yours. *shrugs*
