Just the other day someone I know IRL thought they were having a 'debate' with me on Facebook which basically consisted of throwing ad hominems and mistruths, and I used the word 'irregardless' saying that many people were choosing to reject identity politic labels irregardless of their race/gender/sexuality. He responded back:
"'Irregardless' is not a word."
So yes, apparently this is a thing. I chose that word specifically because 'regardless' was not accurate and because when I told him previously that I did not identify as POC he tried to construe that as me not caring about/valuing/considering my ethnic heritage. Of course, this dumbass works at Google.
