Scorn
Disdain, Contempt
noun, verbal noun
Lightweight scorn, no matter how light, is still scorn. Those feelings are pretty strong no matter what.
This is a jukugo word that uses the on'yomi readings of the kanji. You haven't learned this reading for 軽 yet, so here's a mnemonic to help you:
You have more scorn and disdain for the KKK (けい) than any other group in the whole world. And I'm not going to argue with you, they're pretty hatable.
私、あの人のこと軽蔑しているの。
I despise them.
