levitygravity,
You may notice the title of this thread refers to Koreans. It could be about any nationality. I am unaware of any advantage in ice climbing due to nationality, ethnicity, or genetics. You may notice some funny photos of Korean newbies (gumbies). If you search this site, you will find a huge proportion of photos, criticism, and poking-of-fun directed at gumby "mid-to-upper-middle class white folks".
In my post, you may notice my reference to "Korean" as being applicable to this thread and my qualification of "gumby" denoting skill/experience. In my post, I did not elaborate to include the justification that my judgment of their skill and/or experience was based on age and behavior - the poor judgment of their leader was mentioned based on the size of the group and the stated objective. Again, they were Korean, they were about to be flown in to engage in alpine/water ice, making it applicable to this thread.
No worries. It appears, though the best of intentions (concerns for safety) may be in play by the attempted "dissuader", as was my case, you will attribute the worst...oops, again.
Pity about your sensitivity to being of East Asian descent...
...you oughta see what it's like being a real ugly mofo, as I am.
