But if it’s not hard, if it’s laughably easy as so many suggest with DF, why worry so much about carrying someone?

because it adds a considerable amount of time to things as dungeons, trials or raids
because it means that player will most likely continue to get carried through content and be a burden to others
because it means that player does not want to put in a modicum of effort into learning their class (50+ content)

toxic positivity isn't a good mindset to have. it downplays problems, it enables bad behaviour/habits and it invalidates the opinions, experiences and other things by people that think differently, as seen by the various proponents in this and other similar threads
