I'm sure that for you and others, these things get old and tired very quickly. For that, I apologize. Yes, I do agree with you that it should stop. But it hasn't, and people are getting tired of the subtle and not so subtle jabs. In all seriousness, do you not care that good people are being demeaned?
I think people are capable of considering the source and drawing their own conclusions.
I'm more concerned with the "thesis defense" attitude that often takes over these threads, where people seeking input on early explorations are dismissed as knowing nothing.
OF COURSE they don't know anything! They're beginners!
If the goal really is to encourage the development of internal skills -- as opposed to promoting some personal agenda -- squelching beginners doesn't help.
