No, it doesn't seem snotty to me. I mean, from what you say, these translators are misleading the readers about an essential aspect of how the book reads!

I own FMA and enjoyed that translation too - though I had my nitpicks with it as well iirc. And of late I have been eyeing Donougher in a "do I really need to own multiple copies of the brick" "but FOOTNOTES" sort of way. And given your comments in your first reply to this post I am finding myself more curious to check out what Donougher's translation is like.
