Before one rants about what the halachah is and determines with no hesitation that a given halachic opinion offered here should be disregarded, one should consider the following:
1. Have I ever learned the halachos of hachanah from the primary sources?
2. Do I know how to look up the halachic sources in order to offer a halachic opinion?
3. Is the responder possibly a Rav or halachic authority himself, and if so, who am I to berate him?
4. Am I qualified to determine what is a widely accepted halachic loophole?
Sometimes a bit of self awareness helps.
