Wow, you're right. They do.
The have an entry for the word Irregardless too, but I'd still consider anyone who used it an idot.
What exactly is wrong w/irregardless? Mind you I'm not debating; just asking for clarification.
Personally, I don't use the word as or me the meaning(legitimate or not)is a bit convoluted, what w/the somewhat negative pre- and suffix.
