Some people I will never try to convince. But for this complicated topic I still do not have any strong opinion myself. The discussion forces me to look at (new) facts again. And I learn how different people look at it in total different ways. One huge thing I learned is the saying about the pig. Great way to describe some situations. I posted a link to an article in my other comment. It makes clear how complicated it is and how little we know (although much more than 3 months ago).Good luck, Indah. You are trying to use facts in a discussion with folks who confuse facts with opinions, and cherry pick information to agree with their opinions. It is a losing battle, and not worth fighting. The old saying is, "Never wrestle with a pig. You just get dirty, and the pig loves it."
