In my humble view point, my dear RG friends, posts with frank ideas and view points are far more valuable, reasonable, scientific, constructive and fruitful than downvotings (especially some people play downvotings as mischief games for fun).
It would be really nice that RG can become a scientific research platform with more humanity and harmony atmosphere in which “schools of thought contend and the flowers bloom”------offering a garden for “bees” working naturally and happily.
