Self-censoring is in no way 'a higher level of discourse'. Not using curse words is one thing, but in some situation (esp. like this where a direct quote is used) there is no real reason to censor swear words in an adult conversation.
I know it's originally from a Zuckerburg quote but the point is that if you want to call someone a dumbfuck, call them a dumbfuck. Censoring the latter half doesn't somehow elevate the discourse.
If you want cursing or other low content, there's always Reddit.
