I don't understand why you had to get defensive and disrespectful at the end when I already said I wasn't coming from a malicious place. All I did was offer feedback and ask a question. I wasn't forcing you to agree with me or do something against your will. It's your game, you can do whatever you want with it, and you don't owe me anything.
Just because you've never heard of something doesn't mean it doesn't exist. I'm not sure how you didn't find it, but Google reveals plenty of information about l*me being a derogatory slur rooted in ableism. Its original meaning, taken from Oxford as well, is:
"(especially of an animal) unable to walk without difficulty as the result of an injury or illness affecting the leg or foot."
The "uninspiring and dull" definition only came into existence after people began using it to discriminate against disabled people. Language evolves over time and, as of the present day, words like l*me and r*tard are in fact ableist slurs.
I could continue explaining the history of these words and their evolution into slurs, but based on your response, I don't think you're open to it, which is fine. I accept your decision to continue using such language in your game and will move on. Thanks for the reply and good luck.
