No one like to be criticised.That's why one famous author said don't criticise if you want to win friends.
Sometimes comments are more useful than praises.Praises can just make you happy.
How one reacts to criticism is important.I believe I react to comments on me quite well.
The govt of M'sia sometimes uses ISA to detain ppl whose views it doesn't like.
S'pore govt leaders sue some opposition leaders for defamation and make them bankcrupted.They did so possibly because they wanted to 'destroy them politically'.
