Spreading rumors and calumnies and plotting riots.

造谣诽谤,策动骚乱.

He doesn't care about scandals, slanders, calumnies, aspersions, or defamation.

他不在乎流言蜚语，诽谤，中伤。

Calumnies are answered best with silence.

雄辩是银，沉默是金。（卡莱尔）

I have been too long accustomed to hear imputations and calumnies thrown out upon great and honorable characters, to be much influenced by them.

长期以来，我已习惯于听到对于伟大、高尚的人物的诋毁、中伤，已不再受其影响了。
