truly, this is one of the most ridiculous suggestions I've ever seen.
You can't just remove the disrespect rule.
The disrespect rule should be handled with common sense.
"Who the fuck are you?" in my books isn't disrespectful.
-Though repeated many times isn't a show of respect if not intended by the user.
-People may use "banter" as an excuse for against disrespect which may be disrespect.
Using derogatory terms which fall under racism, sexism etc.. and forms of bullying is.
The definition of disrespect is showing lack of respect and courtesy, whereby courtesy is being polite to others. In terms of fuck, it may be shown as not polite. It all comes down to context.
Conduct yourself appropriately and show politeness to others without the attention of causing harm
