What r-bomb? Retarded? That's an actual word and I used it according to its definition.

I won't allow your misplaced sensitivities to diminish the English language. If you need a safe space then find one, but don't demand I alter an entire language just to suit your desire to be protected from what you feel is offensive when it's not. I did not use that word as a pejorative towards a legitimate handicapped person. I used it in its proper context.
"characterized by a slowness or limitation in intellectual understanding and awareness, emotional development, academic progress, etc."
Feeling the need to carry a 1/2" thick fixed blade knife just because it survived being hit with a sledgehammer without regard to any other factor "shows slowness or limitation in intellectual understanding..."
Feeling that you need an otherwise crappy folding knife with a lock that HAS to withstand 800 lbs of weight on the spine without regard to any other factor "shows slowness or limitation in intellectual understanding..." of what a knife is. Simply showing a knife can withstand 800 lbs of weight or simply designing a lock that is that good is not retarded. Showing a knife can reliably withstand normal use and can also withstand the occasional accident or abnormally rough use is not retarded, or " slowness or limitation in intellectual understanding..."
