Imagine how many fucking arguments people could have avoided if they called the movement “black lives matter too” instead of “black lives matter”.

It's so simple, so obvious...and such a missed opportunity. And while I personally saw the "too" as implied, it led to bad-faith actors really twisting it as well as inevitably some people actually not understanding it.

Same with going from LGBT to LGBTQIA2S+ or other longform acronym that is not as straightforward as LGBT+

The fear of leaving anyone out led to tacking on more and more letters, and then disagreements about which letters to include.

GSM (Gender & Sexual Minorities , which unambigiously covers everything).

I haven't heard this one before, but I like it for its simplicity.

"Defund the police" was another fail in that the phrase didn't accurately portray the actual intention and was off-putting to people who might have otherwise supported it.
