The original post just had "White people love playing 'divide and rule' as the quote, which is a generalisation and probably would justify an apology as it is about race, rather than a throwaway subject where generalisations are made day in day out.
However it is the second part of the tweet given on Wikipedia I find more of an error of judgement and offensive:
'We should not play their game'
Coming from a politician whose party is committed to promoting and embracing Britain as a multicultural society I think that part of the quote more worthy of disciplinary procedure.
See what I mean about people ignoring the hash tag, even when they split it up into two halves and quote it verbatim they still don't get it
