Personally, I learn a lot from debates. I learn nothing from arguments. If you keep your opinions respectful and keep an open mind, I think we all will learn.
Honestly, the only reason I come on here is to learn and to see harvests. I wouldn't have stuck around for 3-4 years if there wasn't any of that being put out here. The 'pot stirring' is only done by one, maybe two individuals so I mainly ignore their rants and move on.
Life is way too short to get all worked up over someone else's opinion.
