I don't know if rock was thought to be banal, that's the wrong word, certainly influencing rebellion and some thought Satanism. Just like the fear mongering of Communism in the Cold War age, there were large vocal groups of rather ignorant mob mentality running around, my parents never cared to listen in depth to rock music, and they STILL don't, but it took my calm head to convince them this music has it's own merit, my dad still hates it though, my mom will listen to soft rock! hahaha They hated me having Ozzy's Blizzard record in the house, like the band KISS, I was in the Kiss Army long ago! I guess I still am, and my dad certainly didn't like me having a Sam Kinison record under his roof, again there was plentiful cursing there too, but Sam was coming from a religious family and was himself a preacher! He never denied God or Faith, but he also dabbled openly in temptations. We're all human like that, and that's a point I drive home still.
Guns in the real world hold no interest for me, I don't plan to buy one anytime soon, but in games, you need them, the games we like, it's all virtual reality, no harm no foul. Problem is there's foul in the mortal world, and how do you deal with it!
Even as gamers, we should take a responsible side/stance
