I grew up using this word all the time. It’s just one of the dumb words we said all the time. I only found out within the last couple of years that it’s considered a slur. Idk, I feel most people who are actually considered retarded and are competent enough to understand don’t actually care. But the reality is that any sort of “name calling” isn’t necessary. I grew up with a culture of all sorts of name calling, but just because I grew up with doesn’t mean it’s right.
But ultimately, language and the world changes and it’s just not acceptable to say anymore because it is derogatory towards a particular group.
There was a Twitch channel that featured AI Trump and Biden debating. They’ve changed it to Trump and Kamala now https://www.twitch.tv/trumporkamala2024 might be worth a watch for such content.
