This kind of pretend action is worse than doing nothing - because not only you feel better about yourself and don't do anything actually useful - you also discourage people who actually want to do something about the real problem.
This is the reason people think liberalism and social justice is a meme. This exact shit.
Besides - do you know where the word "slave" comes from?
It comes from Slavic word "słowo" which means "word" (it was written differently in proto-Slavic, but whatever). "Słowianie" mean "people who speak words"="Slavic people". In English it's translated as "Slavs".
Słowianie were the original slaves, to the point that Latin used their name for the word "slave" (sclava) which was later adopted by French and English with small changes.
What will you do about it? Invent a new name for all the Slavic languages and people related to that word?
Slovaks/Slovenes/Slavs/Slovakian/Slovenian/Slovakia/Slovenia/slavic?
Do you think it's "tone deaf" to use a word for "slave" that comes from name millions of people call themselves? Do you think it warrants change of language? Why not?
