> It's considered that by lay people, largely due to Korean patriotism, not by real linguists (can you provide a source?)

I didn't say the MOST, it's among the more scientific languages. I'm not pushing for Korean patriotism, that's just your own assumptions.

> So, you're talking about the alphabet used to write the language, not the language itself. At best you've proven that Korean has a highly regular writing system. But I'd argue that the average HNer could learn to read, for example, Spanish in about two minutes.

Hangul is the writing system that is uniquely different from a latin based system like Spanish. Your argument is moot.
