You know that the word "irregardless" passes spellchecks. So look at the word structure. Without having lack of regard.

Just because you can point out an idiotic definition in the dictionary doesn't make it less ridiculous nor redundant.

How about you simply stop being sensitive to some response from a random person you will never ever meet in your life on the internet that just wanted to educate you so that you can better present your obvious intelligence to those who DO fucking matter.
