I think you might be on the wrong side of the argument here, as others are pointing out the ‘quiet’ part of that sentence isn’t meant to be low volume, but more along the lines of secret or unspoken, and the ‘out loud’ part doesn’t mean volume, it means ‘spoken’.

If it helps, it’s like when someone says something they were thinking and goes ‘oh no, did i say that out loud?!’… They’re not specifically worried about how loudly they said it, but that they said it audibly at all when they meant to only think it.

Ha, imagine being a troll and having to read ‘Lowes’ as the takeaway to your post just to come up with something edgy.
