"road rage" works very much the same as what people get when there on the computer. they feel extremely safe behind there screen and have little fear to express there opinion to other people.
however sometimes it's good to get extremely honest feedback. there were times when I was practicing music at home and asked my friends/family if it was good, they weren't honest and it just hurt more when I got negative feedback for the first time at college. I made a minecraft texture pack, and the first response was "it's &&&&, the colours just seem random" I went back and made a pallet of colours and made sure each biome fitted with these. I could of had the knee-jerk response like many have "well it's just not your thing then" buts terrible at ignoring the first real feedback of a random person who tested it for me.
it's up to us as a community to promote constructive feedback, for example: "I hate x because of y". even if that means asking just asking "why?" do they hate elements/mechanics of the game. just ignore obvious trolls too, shouldn't need to be reminded.
ofc, it could just be "grumpy old man syndrome"...
