@aSimpForHotGuysExceptForJaekyung because the word "retarded" was used to classify mentally disabled people and systemically oppress them. Most infamous usage of the word ret*** was used to describe physically impaired people, autistic people, and people with Down syndrome or learning impairment. Being called a ret*** was basically like saying, "because this person is different their useless, dumb, and overall unfit for society" it was a term used to completely invalidate one's worth. I would think you would know better since it's 2025 but hey, it's not like googles at your finger tips. 

Spoiler!
I ❤️ you :D
