Hello MHK,
Good on you to educate Mg Aung Thu in the voting system. If he had voted 'No' and said 'I didn't care whether they know it or not, because it is extremely important to officially express my opinion on their draft constitution', then why bothered about it. Most of them look out for little negative and expand it to demonised the whole process. If you don't have these numbers, they will also accuse of rigging the ballots. You can't win with them anyway. 'Empty drums make more sound' or 'Little knowledge is dangerous. as they do not want to learn.

I am Polaris.
