I don't think that's a serious barrier in this case. The above poster just would rather dismiss a statement rather than give it serious thought. It's easier to simply claim to know the one true meaning of "simple" rather than actually communicate effectively.

Trying to understand the speaker, presumably, and not wielding your pet definition like a semantic argument. It's fundamentally boring conversation with no benefit to either party and it makes you look like an illiterate ass.
