Calling a lie a lie, and GD

This is dealt with in a sticky in GD. Post 2 addresses this situation:

So I felt the “lie lie lie” comment ran afoul of that rule, keeping the last two examples in mind. There’s no shortage of ways to say that a post contains errors without calling the poster a liar. I thought this situation was fairly straightforward, but if the other GD mods don’t agree I’m happy to reconsider.
