Not a discussion. You haven’t discussed what they mean by a tortle, what aspects of tortle they think will work well in the campaign, and so on. And of course because “tortle” is a hypothetical, no one who is posting here could give you a true answer.
I have seen a few people give answers to why hot a tortle (whatever). That come across as “because my world building is more important than making the game fun”, which I suspect the posts you are thinking of where responding to. “Because tortles don’t exist in this world” is not a good answer in a world of magic, because they could be mutant terrapins or from another world. “Because everyone hates tortles” is not a good answer, since being hated by NPCs is something players are willing to deal with (see 2nd edition drow), “it doesn’t fit the theme of my Conan campaign” is a reason - to play with different people, because the player clearly isn’t interested in that theme.
I tried. I really did. I finally came up with tortle man post 9829476 and was told it was not good enough because it wasn't a tortle.
As far as why I say no I've explained it many times. Nobody has explained why I must say yes when I already tell people what the limitations are when I ask if people are interested in joining my game.
