"I'm not really interested in the rights or the wrongs of Helen's tweet." in other words you do not care about truth and JUSTICE. 
Here are more truths you will not like
Mmusi, contravened his parties FEDEX's instructs when he declared Helen suspension, the FEDEX had clearly stated she was to face a hearing first.
Under leadership of Mmusi the DA has taken drastic measures against all whites who over step the racist line such as Penny Sparrow, yet they have taken no action against blacks who do the same. Even when informed about black people calling for the mass murder of whites, and being sent proof of these statements the DA has refused to take action. 
Couple the above with the fact that the DA itself has said no matter what Helen MUST be fired to ensure the DA gets more black votes, and it clear that the DA is no longer a non racial party, but their hunger for power has made them turn their backs on minorities, whom the see as nothing more than sacrificial lambs to get black votes.
