All these for about 30 years. It was not a short time to correct the misguided decision, if mistake was made at the onset and has been recognized afterwards as such.
Now it is un-Oromo to show off power or take a pride over winning over one's adversary and sing about winning over those who were misguided, it is not in the interest of the people to people relation in the future, which will remain even long after those responsible have been gone (on both sides). It is not in-line with the idea of reconciliation and forgiveness stated at the onset of the current reform as well.
I think it was Mitchell Obama who said very recently something like "when they go low and lower, we go high and higher, we will never allow ourselves to get to their level".
If they have lost, then just forgive and move on, it is unfortunate chapter of our history.
For the record here: this is just a flash-back of archive videos, presented without any comment, but I thought it is untimely to show it in such a way at this time.
