Last time I saw it used regularly was on edgy internet forums in like 2003 by the same people trying to say that the n-word isn't racist because they only are talking about the 'bad ones'. Maybe what happened is polarization where people who don't want to be racist accepted that broadly disparaging ethnic cultures is also bad, and people who do want to be racist decided that actually it is about genetics more than culture, so it stopped making sense for anyone to say.
Yeah I was about to comment. Like, imagine using the word "wigger" unironically in 2009, let alone 2019 when this post is from. Hopefully anon can step away from 4chan for a while and learn some good habits from this Chad.
