i don't like it, but there are some justifcations for using double negatives... not irregardless, that one just sounds stupid... but something like "not unfortunate" where the double negative is split, there taken to mean that while it wasn't unfortunate, it wasn't necessarily forunate either...
they can be useful for accurately portraying the middle-ground/uncertainty
i can't actually think of any sentence that needs irregardless... "regarding..." creates a completely differen sentence to "regardless..." but irregardless seems to be a round about method of not actually saying anything
