There's a fourth layer of meaning you may be overlooking - the willful misinterpretation of the term used by its opponents.

One obvious example being the use of "all lives matter" and "blue lives matter" to reinforce the false interpretation of "black lives matter" as meaning "only black lives matter," when the phrase more correctly means "black lives matter as well."

Or the way that "fake news" has been re-appropriated to refer to bias within mainstream media, rather than literally fabricated stories and memes posing as news on social media and the web.

Or ask a feminist and a redpiller to agree on what "toxic masculinity" actually means.
