My point is best illustrated here:
http://www.quickanddirtytips.com/education/grammar/irregardless-versus-regardless.
"Some people mistakenly use irregardless when they mean “regardless.” Regardless means “regard less,” “without regard,” or despite something. For example, Squiggly will eat chocolate regardless of the consequences.
"The prefix ir- (i-r) is a negative prefix, so if you add the prefix ir to a word that's already negative like regardless, you're making a double-negative word that literally means “without without regard.
"Although it's true that the American Heritage Dictionary, the Merriam-Webster Online Dictionary, and the Oxford English Dictionary all list the word irregardless, they also note that it's considered nonstandard.
Listing a word as nonstandard is a way that dictionaries concede that a word is in common use, but isn't really a proper word. Standard language is defined as the language spoken by educated native speakers (1), but comprehensive dictionaries also include nonstandard words, dialect, colloquialisms, and jargon--words like ain't, conversate, and irregardless. It seems pretty common for people to look up a word in a dictionary, and if it's there, they think it's fine to use that word every circumstance. It's the "Look, it's a word!" phenomenon. But you have to look a little further to see what kind of word it is, and if it's nonstandard in some way, then use it with caution.
You'll sound uneducated if you go around saying things like I ain't gonna conversate with him irregardless of the consequences."
Words are important. I am under no misconception, "irregardless" is not a proper word just like "conversate" is not a proper word. I doubt anyone here means to say "without without regard." It's nonsensical.
