Toxins

Ill intent and disingenuousness poison language by tainting its elements, from words to entire conceptual frameworks, with the idea that those elements exist, in whole or in part, simply to mask the hatreds and prejudices of anyone who utters them, and are thus reliable indicators of bias and/or malice.

This has the effect of not only declaring entire sections of language off limits in polite company, but it denies people access to avenues of communication that are not replaced; and it often does this unilaterally.
