Besides, if you've ever EVER felt bad because of something someone said to you you're a hypocrite and should be ashamed. And given how cruel humans can be, I'd like to see you say you haven't felt bad because of a few letter puahed together.
First off, how would being upset by some word said to me at some point in my life make me a Hypocrite? The only way that would be the case is if I was sitting here telling people they need to just ignore mean words and grow thicker skins, but then I myself was still being offended by the same words and trying to get people to stop using them.
Yeah I've been hurt by words said to me in the past. who hasn't? The difference here is that at some point along the way, I decided words are just that. Words. -and I thus decided to stop letting them have power over me or affect me negatively, because at the end of the day, I don't really care what word some Rando passing by says or some troll on the internet types to try and get under my skin.
Unfortunately there are going to be people who no matter what get hurt by words, for various reasons, sometimes uncontrollable by them.
However, forming interest groups with the specific purpose of trying to control and maintain the negative connotation with certain words is actually more harmful on society if anything. In most cases it's seemingly done with the intention of these groups having something to call their own, some ammunition that they can use against people who they deem privileged to in fact, get them down.
How about instead, marginalized individuals- or at least the people who represent them- form interest groups who's goal is either disassociation with the negative connotation of a word, or maybe trying to turn that word into something with more of a funny, neutral or even positive connotation? It's because the answer is simple. It's about control. It's about wanting something that gives you power over someone else.
Even if that power is just the ability to tell someone they're not allowed to use a word because it's "offensive", and then in turn be praised by your peers for verbally abusing someone with every slanderous word under the sun just because they used the word "Retarded" and you were "checking their privilege".
