I see football fans defending the Asian Games national team

Why are they doing that? Are there a lot of brainless people out there?
I've been a Man Utd fan for 20 years, so I'm a die-hard too, but
looking at the accounts of those defending the controversy surrounding the Asian Games football interviews on Instagram (excluding burner accounts),
most of them seem to be football fans, including many young kids.
I don't get why they're so resentful that they're choosing to get insulted in a losing battle.
ㅋㅋ Don't they know that military service issues in Korea will just absolutely destroy you?
