speak up or shut up?

how do people differentiate between destruptive criticism and contructive comments?

sometimes reading news..or rather public's comments on news can be quite irritating. i wonder if it's just me or it's the nature that things are. people who are kb cant shut up..while the opposite dont speak up. maybe...just maybe..people who speak before they think tend to give extreme comments..while those that think before they speak realises that there is no point arguing with them. lolx.

i suppose it's also a skill to give comments. sometimes i just feel that there is no point screaming out the truth even if you are right, less others are willing to take it in. otherwise, those words will just become meaningless criticism that stir conflicts.

words are amazing thing that human creates. it can motivate, can inspire, can be use to communicate and can also to record. but it can also easily create conflict, can hurt people, or even kill...

if you think it matters, then choose your words wisely. otherwise, shut up. lolx.
