Oh, I see. That definition gives me a new perspective... I always thought of it as ableism.. before online spaces, and even before the word ableism came to my life. As a kid, I always heard that using retarded as an insult was wrong.

I guess I will have to add this to my todo list, right after invention of time travel ;p hehe. Imagine a kid quoting the dictionary to an adult.

In any case, your comment stays and my person has learned something new for moderation, beyond this terminology.. the context is very important. I actually felt like removing the comment would have been wrong. It seemed your words were too harsh but still, they were going for a point, without raw intent to insult or carry any ad hominem fallacy. I see my instinct was right :) hooray!
