CSJ and the rest of the opposition need to realise a few things:
1. They are held with the same, if not more, contempt that these two siblings have for their brother.
2. The two siblings are in a way better position to fuck up their brother than Chee or any of the opposition can ever do.
3. They will will come across negatively as opportunists seeking to capitalise on a he-said-she -said "private" family feud.
4. Lastly but most importantly, they need to get this into their heads, i.e. blood is thicker than water.
What Chee and the rest of the opposition need to do is to shut up, let the duelling be drawn out which will allow for more damaging shit to emerge instead of allowing the shit to subside or go underground each time they open their mouths thinking they can score some political points of this saga.
