The Polite Type – Automatically replacing hurtful words with more inclusive ones

Good try, three problems. 1) non-aggressive uses of potentially hurtful words will be modified and annoy people. i.e. 'bitchin' as in "cool", "dope", or "rad". i.e "hoe" as in "garden hoe" (not the sexually attractive gardener)

2)You're missing some nasty words. i.e. "chug" : An extremely offensive term for First Nations people in Western Canada. Every local area has its own variations on things. Even if you were to figure them all out, languages evolve constantly.

3) phonetic varients aren't yet replaced. i.e. feggit,f0k,
