You're losing credibility quickly, Kwang yi. Personal attacks detract from any real information you may provide.
Your credibility comes from sharing knowledge, not by playing politics.
Someone of no knowledge telling, "I have 0 tolerance," I'm done with this stupid forum. I spend enough hours trying to fix badly published information, a personal opinion of how things are made with flawed and uneducated knowledge, and you people cannot accept the truth, truth based on 200 years of scientific knowledge that is widely taught in public high school level physics,.. I'm done.
People get pissed when I do not follow an advice that has nothing do to with question posted, I'm done.
My time is precious, I don't need keep reading posts that is wasting my time, that is becoming depressing for me to swallow because these kind of information should be taught in public school, and people of no basic education should be stopped spreading false science.
I'm worry to death how our children is falling behind academically. This is becoming too depressing, like watching snake oil salesman is screwing everyone around me, and I'm sitting helpless watching these phonies spreading toxic air.
