Why are users so condescending here?

I’m not understanding what’s with everyone being so pretentious and condescending towards espresso noobs… we’re not talking about single button coffee machines here. I’ve gotten a lot of really great constructive feedback from this sub but the delivery AWFUL. With all that being said, I have a KINGrinder K6 coming in the mail today — anything I should know about this grinder before I get dragged through the mud for not knowing? Tips are appreciated
