"What's funny about LRD using the word 'disablist'"
It is funny because all OP said was that she won't debate with people who write could of instead of could have, the vast majority of whom will have no disability whatsoever. LRD calling her "disablist" is ridiculous.
Going by that line, it is disablist to criticise any behaviour, since in every population there will be a few people who genuinely can't do it even if they try.
Even more ridiculous is her falsely accusing me of laughing at disablism because she apparently thinks "disablist" (in quotation marks) is the same thing as disablism (a different word, without quotation marks). And this is apparently a "disagreement" in her world 
I know you want to be on her side because you are fellow FWR regulars, but seriously...
