Toxic communities online always share the same core issues.

Overly defensive (from low self esteem), self centered (from acting superior all the time as a by product to cope & bolster their low self esteem) and uncharitable with their time & patience for newcomers and people they see as unintelligent (going back to acting superior, again root cause of low self esteem).

Sadly these characteristics are far too common in the tech world. Not everyone is lacking self confidence and those with the most can sometimes go the furthest.

However online anonymity gives people who are socially damaged a cloister of like minded, sheltered, angry people who take out their frustrations on each other and any random who stumbles into their coven.

Their common method of dealing with people on the Internet is the only way they know how...to push people away even further away. Ultimately their goal is to not expose their greatness weakness to others (their lack of self esteem). Their lack of self esteem makes them socially awkward which immediately gives others the upper hand in their mind. They avoid being exposed, or rather reminded of their self esteem issues, by acting rude to everyone but a select chosen few.

I have been playing games and doing coding and been in so many online communities over the last 20 years.. Toxic communities always boil down to the same drama. It's all kids who used to be picked on, but never learned to grow up and cope with adversity. They stayed damaged goods forever and as adults perpetuate what happened to them on others, sometimes without realizing it and sometimes knowing about it and relishing in it as some sort of cosmic balance.

What I learned early on is when I spot a toxic community in something I really want to be part of I look for alternative communities and if everyone shares that mindset of negativity, sometimes I just move on. It's sad when people grow old but never can learn life coping and life thriving skills. People who shelter themselves never have a reason to grow or challenge themselves in these ways.
