And while I'm on the subject, D&D is a game that should be entry level. If too many people are hitting their thumbs with it then it's a flaw in either the design of the game or the use of the hammer.
It would be clearer to see with a power tool; if a band saw were to take too many fingers then you could blame the fingers lopped off and some amateurs would. On the other hand any responsible professional environment would do a health and safety check and realise that the whole thing was unsafe and look at installing finger guards.
One person hurts themselves is user error. A substantial fraction of people hurting themselves means that you look at the design of the tool.
Yes, the most successful TTRPG in history is failing miserably because someone somewhere might misuse alignment. Oh, and alignment is defined by what some dead guy said decades ago.
On the other hand, if people are using alignment in a way that is not approved by the Anti-Alignment Police but still having fun, why does it matter to you? If a group decides that creature X is always evil and go out to exterminate every last one, why do you care? If someone somewhere decides that orcs in their world are all LOTR orcs or controlled puppets of Grrumsh why does it matter to you? If you don't like that style of game, don't join that group. If you don't like alignment, don't use it.
The
current official materials significantly downplays alignment, when it even discusses it at all. There is no more cosmic orientation by alignment. While I do believe it should be clearer, the alignment of any creature in the MM is just a default, it's not set in stone. The official published settings all have exceptions for at least some monsters. It doesn't matter what some dead guy, even Gary Gygax said who knows how long ago. In the current edition, alignment is just one descriptor of many for PCs. It's just the default for other groups, a quick label that gives DMs and players a general idea of what this fictional creature's role in the game is.
Some people just want to play the TTRPG version of DOOM and don't care what categorization the monstrous opponents have. Some people probably want to play My Little
Pony Dragon where all conflict is just a misunderstanding and we all just need to hug it out. There is no wrong way to play as long as everyone at the table is having fun.
Oh yes. Their personality is "Lawful Evil." That's not a personality unless you're playing a comedy game based on Saturday Morning cartoons.
Again, no one is saying alignment is all encompassing. But even if it is for some groups, why do you care? How is it a problem?
