argue, biased, one-sided
詖 centers on speech that is not balanced or fair: arguing in a biased, one-sided way.
詖 combines 言 (speech) with 皮, which likely contributes the sound and may suggest a surface or outer layer, giving the idea of speech that is superficial or one-sided.
Words (言) that are like a skin (皮) only covering one side: biased, one-sided arguing.
For ヒ, imagine a heated argument where someone keeps saying 'He!' (ヒ) to point out the other's bias.
