see again... instead of talking about any of the examples of "Hey lets all be adults and talk about me not having fun because I feel overshadowed" you jump to "crybabies" and "throw dice" please tell me any anti roll stats that have ever said that is how we would react?
here comes the some insults... infact so bad that I can't belive it's a mistake. You equate someone saying "Hey I don't think rolling stats always ends up with a fair spread" or someone saying "I'm not having fun here my stats are far lower then his" with those cry babies... even if they are perfectly adult and polite in how they raise the issue...
It's no mistake. Rolling stats doesn't lead to a fair spread, because life isn't fair. Why should D&D worlds be more fair with respect to one's mental or physical attributes than it is in real life? Why should PCs be spared the harsh reality that every human being is subject to? Oh right, they aren't. I allow point buy, so you can skip it. But point buy doesn't lead to exceptional PCs. You pick, risk some negatives to get some higher pluses, or take the safe route. That is so fair it's almost mind boggling that anyone would even consider it unfair.
I don't want every PC to have the exact same total bonus. Low bonuses often lead to interesting characters, because they tend to work harder to get good, don't rush into combat every chance they get, don't do reckless things, and tend to play more intelligently and consciously and get more immersed in the story.
I don't see why everyone should be Conan or King Arthur in a fantasy RPG. Or one two exceptionally strong or intelligent PCs per group is more than enough. If you want to be perfectly adequate, choose point buy. But then you have 0 chance of having an 18 at level 1. If you want to risk it, to get higher than 16 or 17, then you can. Up to you. Pick up the gun, or walk away. Take a chance to double your money or lose it all, or walk away with what you have.
You can get a 20 in your main stat after a few months of playing, no matter what you rolled, anyway. This makes the "unfairness" of rolling not giving the same maximum bonus each time completely moot. That kind of nit picking every last +1 matters only to min maxers, in my experience. I like min maxing too, so I usually risk it all to get at least one 18. An 18 in your main stat usually matters more than your total stat bonus anyway.
You could have a perfectly viable PC with 18, 10, 10, 8, 8, 8.
Don't take personal offense when none was given towards you. It's uncalled for. This is small potatoes. The much bigger deal here is the idea that you have to be able to deal with low dice rolls when you sign up and join this game. If you can't, then no, I don't want to game with such a person and do consider them crybabies and will call that to their face. I don't mince words, people like that about me. Bluntness is honest.
If you think your character is "overshadowed" by a single +1 advantage by your neighbor, then yes, that is by definition what a "rollplayer" is. It's not like using point buy doesn't lead to viable characters in 5e, it absolutely does and by level 4 or 8 you will have that 18 or 20 and be caught up. If you then complain about not using those slots for feats, then yes, again, that's what a powergamer is, and I have zero sympathy. Cry me a river.
The dice are King in D&D. Respect them. Kiss the ring. That's what D&D is all about. If you can't handle randomness (which is inherently unfair from the point of view of equality of outcomes), don't play a dice game.
