I don't think people are knocking you and I think the post you wrote about why you choose UL was spot on. If it's what you enjoy that's all that matters. Most of the troll stuff is directed at Chuck, who may or may not realize how close he sounds to another character.
Of course weight matters, but it is a case of varying degrees (personal enjoyment of the pursuit aside).
For racing it absolutely does. For light/fast rides where distance/time matter it's important too. And, even with straight up traditional touring, it makes sense to be sensibly aware of weight - but not to an obsessive degree.
One way to look at it is to determine what the average rider uses on an average tour. If for some reason one thinks their weight needs to be either overtly heavy or light one ought to ask themselves what that reason is.
There may be a perfectly good reason - or it may be fear based regarding comfort while riding or comfort while not riding. People can get crazy either way.
