I've never been "JJ" but I know he's got friends who are Asian and they don't mind being referred to as "hamiltons". They just see it the same as scots being called "sweaty socks".
I find it rather presumptuous when 'whites' claim offence on the behalf of people of different colour who themselves have taken no offence.
Virtue signalling at its worst. If it makes people happy fair enough. Go for it.
