I get that and agree that rudeness should not be tolerated, but the idea that you either buy the knife or don't is not really a realistic option. If someone came in and said here is the 2019 BF knife, where it's ready to go and there was no selection process involved, then the idea of "buy it or don't" would apply. But, when you are asking people to be involved in every step of the process then I don't think that logic applies.
Also the idea that people want to enjoy the process without being bothered by disappointed people is also a little unrealistic, it just isn't going to happen. The disappointed people want to enjoy the process too, they just don't because they are not getting what they want. As long as you allow opinion to be expressed then you will have to deal with the good and the bad. Just my opinion (that doesn't count for much).
I will say that its been interesting, as this was my first time participating in this process in this sub-forum, and I would like to express my thatnsk for the people that make this kind of thing happen. Thank you.
