I think if more people used the dictionary wisely there would be less problems. If you are claiming to be something that you are verifiably not by a simple reference to a dictionary, then you need to cut it out, its lying.
Yes, it is the place of human beings to criticize others if they are being deceitful, even more so if the deceit swindles from the less fortunate.
Here are a few examples:
“Celt or Kelt (kɛlt, sɛlt) — n1.a person who speaks a Celtic language2.a member of an Indo-European people who in pre-Roman times inhabited Britain, Gaul, Spain, and otherparts of W and central Europe” and
“Celt [kelt, selt] Show IPA noun a member of an Indo- European people now represented chiefly by the Irish, Gaels, Welsh, and Bretons.”
So if I say I am a Celt, I am correct for two reasons, first because I speak some Gaeilge. Secondly because my heritage is Irish. A person with no such heritage, but speaks Gaeilge (or another Celtic language) would still fit into the definition and vice versa. (Honestly, most people who live in the Western world have some amount of Celtic heritage, this isn’t really one to fight)
Here’s another couple:
“witch 1 (wɪtʃ) — n1.a person, usually female, who practises or professes to practise magic or sorcery, esp black magic, or is believed to have dealings with the devil 2.an ugly or wicked old woman 3.a Wiccan priest or priestess 4.a fascinating or enchanting woman 5.short for water witch”
“Wicca (ˈwɪkə) — n( sometimes not capital ) the cult or practice of witchcraft”
So a person claiming that Wiccans are not witches, would be incorrect. And a person claiming to be a witch that doesn’t do magic would have to be either an ugly or wicked old woman or a fascinating and enchanting woman (I say that part tongue in cheek because both are references to the first definition to say they seem like a woman who practices malevolent magic) or a dowser.
I have done a whole series on what you really meant to say and I could go on forever. But a huge amount of ground would be covered if people just used their words more correctly.
Now it just is not useful to go around tumblr correcting everyone who uses language incorrectly. Hopefully someday they will pick up a dictionary. The current trend is to make all non-indigneous based terms to mean absolutely anyone who wants to call themselves that and any indigneous based term to only mean the originating culture who coined it despite hundreds of years of academic use for a slightly more general purpose. The better answer is somewhere in the middle. Lets stop continuing to expand the use of indigneous terms to mean whatever whoever wants it to mean at the moment and at least stick to the academic and dictionary meaning. And lets stop expanding the other terms to mean anything and everything when there are perfectly already other perfectly good words for those folks. In my opinion 90% of misappropriation would be halted.
Using my examples above, a person who had no connection to Celtic language or peoples and who did not ever do any magic would not call themselves a Celtic Wiccan nor Witch. Now I chose these examples because I fit into these terms, Celt and Witch.
Now people don’t go around campaigning for Celt and Witch because they are not also social justice issues. That is huge! The damages done to Ireland by England have mostly been atoned for—reasonable treaties have been done and for the most part Ireland governs itself as it pleases and has the money and resources to revive nearly lost language and culture. Whereas in the US today, the damage to Native Americans is still just awful. We have a racism and cultural and violence and resources theft issue that is still very very current and pertinent. Languages still completely die out and so do tribes. Native American is a legal term that has an clear meaning on how you are related to a tribe). So if one doesn’t have tribal membership, probably best not to identify that way in most case. Not all causes are equal because they come from different levels of enfranchisement in the first place some are already way further along than others.
