4channers use Normalfag. "Normie" is the sanitized version for Redditors and Youtubers that are too afraid to use the -fag suffix. Same with the "Glowie" meme.
In that case, I think this conversation may be entirely wrong as "normie" is in no way a new term, and it's not fear keeping people from using the suffix/slur so I don't think people would go looking for a safe alternative.
