No. I had similar experiences when learning Korean in Korea.

There is a trend by native English speakers to bash english, and treat it like no other language can have any of these issues.

The only major difference is noted in the other response; English has a lot of different dialects. Korean has Standard Korean that everyone learns now, and unofficial regional dialects. With English you have people randomly learning American English, UK English, Indian English, etc, which all have various differences in vocabulary, idioms, grammar, etc.
