Why do a lot of asians praise koreans?

Just because they appreciate the Korean culture does not mean they don't feel the same for their own. That's like saying it's wrong to idolize American music when you're Asian. Like it's wrong to like European music because you're American. It isn't a sin to like other music, is it? Much less other countries. And it isn't a crime either. Korean idols deserve all the respect they're getting anyway. Production for music and videos is EXPENSIVE, so they don't even keep that much of what they really earn. They work hard and they love it, even if it puts so little money in their pockets.
