i'll be Switzerland here, just ignore all of those people you don't agree with, you'll never change someone's mind on that, it's a weekly source of arguments here.
Really, the "ignore" feature is a damn great feature.
I don't agree with a large amount of people on this forum, and with the absolutely insane amounts of different methods and techniques that cannabis can be grown with, it's a super, super easy plant to grow, and in the end, if a grower has been using his or her method for years and producing fantastic herb with said methods and techniques, it'll be hard to convince their way is wrong (often the plant grows in spite of all the extra shit people do to it)
point is, you aren't going to change anyone's beliefs.
Just ignore it, and find another topic to add some information to.
Or not, and shit in your own fishtank by getting upset over it.
It's your world, if an internet forum argument is going to get you riled up, then maybe it's good to ignore the controversial topics.
I'm not saying i'm better than anyone, I've had my share of disagreements, but all it does is piss you off in the end, and that only hurts yourself, hence the "shit in your own fishtank" analogy
