Is it that deep or is it not

I'm friends with this guy who introduced me to his friend group and eventually over time I got somewhat close to them too but I am only truly friends with that one guy. His friends are cool, theyre nice and have never caused any problems or seemed problematic to me until I found out that theyre all used to 2 other guys (white btw) that say the n word constantly and no remorse whatsoever despite preaching to hate racism, overall woke and using woke terms all the time.. I have a bad feeling abt my guy friend who's also white and who doesn't say it at all yet he still hangs out with them that say it

Ive even subtly discussed it with him and in case j was wrong I asked him their race and they are indeed full on white... I know most people don't care about this word and just say it cause it's "just a word".. I could care less abt those bigots but when it comes to people close to me I feel so uncomfortable but since theyve always seemed so nice and genuinely normal people I'm taken aback and I know my friend won't ever try to take it seriously despite he always says he wants to better himself and educate himself but now I see him as a coward and I feel no interest into talking to him anymore yet I'll miss him

It's just disappointing and idk what to do.
Yes it's so corny thinking of a solution and coming here to ask but I'm ready for the worse enough to bring me closure
