Accurate terminology is important–for example, calling everyone under the LGBTQIA umbrella “gay” would be pretty dismissive/marginalizing to those who aren’t gay.
I disagree. Language is fluid and words mean what society wants them to mean. If a society wants to change a word’s meaning, then it changes. There can be an “umbrella” word to encompass the whole umbrella without having to explicitly enumerate each individual sect within it. Other minority groups in society don’t have to do this. I mean, what if the Native American tribes wanted to be known under the umbrella of combining the first letter of every tribe? The term “Native American” does not inherently marginalize the Cherokee or the Osage tribes.
I’m sorry, but I really feel that to be offended or feel marginalized simply because a community’s acronym doesn’t explicitly include one’s flavor of eccentricity–that, to me really is indicative of one who is highly-oversensitive.
