I can't tell what you're saying "nah" about. The comment I responded to said that, to a Western ear, [pap̚] vs [bap̚] is a "very big difference" that isn't noted by the Korean writing system, because Korean cares more about aspiration [of stop consonants, presumably] than voicing. It was in English.

I observed that English shares that quality with Korean, and English speakers are not even able to hear the difference between [pap̚] and [bap̚], making this an odd choice to exhibit as a "very big difference" which will, by its lack of representation in the writing system, confuse English-speaking Westerners. It's a difference they can't perceive; why would they be confused over the fact that two identical sounds are both written the same way?
