Dungeons and ANGRY PEOPLE !

This is the false equivalence trap that you've got tricked into. Yes the both can happens, but odds of it happening is like 500 (experienced players cussing out new players, especially speed runner) to 1 (the nutty new player who thinks too highly of themselves.) The two are side are remotely equal.

Irresponsible blanket statements like that is unfair and unjust and is really mean to OP.

You are being awfully selective regarding what I said, so much so that you actually edited out the part where I stated that neither all new players or all veterans are jerks and a persons experience with these groups of players will vary.
That seems like a fairly open-ended statement with lots of room for variation.

Also, I have not been tricked by anything. I know the generalized breakdown of veterans being nasty vs. new players being nasty, just like I know that doing a side by side comparison is not necessarily going to yield decisive results since there are more elements to take into account such as the percentage of new players vs. veteran players as a whole, how one chooses to define whether a player is new or not (new to the game, new to the content, etc.).

Simply put my statement was laying out that both sides are neither fully right nor fully wrong and that jerks will exist within either group. Things are not black and white with this and really everyone should just try to be a nicer more understanding person.

But the variation is not a 50/50 split down the middle. That is the false equivalence that the "variation" misleads. It is more like 500 to 1, where speed runner are berating anyone else that isn't geared enough, or experienced enough to do the speed runs.
