Yeah, I totally agree. The only thing I can guess, aside from people just being assholes, is that someone with many years of experience is only thinking of what they liked after gaining that experience.

For example, if someone learned with Debian and then moved on to Arch, they think Arch is “better” and I think they are telling others to not waste their time on Debian. They are totally ignoring the fact that they spent quite a bit of time learning before they moved on and they are advising that a newcomer skip to what they perceive as “the end.”
