If for someone like GG it were normal, and he knowingly does even though people will be offended, would be shock tactician (i.e. he believes in it).
People are shocked no matter what. Can't help it. By even saying you like Noise, you shock so many people? Is that your intent? No. But, you are inevitably shocking to people, even and especially if you are just being yourself.
So, things catch on to trends. And suddenly things aren't shocking anymore because more people accept and tolerate behavior. By being honest and genuine, like in Noise or even GG case, things can still be shocking, even if you don't intend them to be. It's a matter of exploring new avenues, which is all shocking is, and why it changes from time to time. So, someone who makes shocking music for sole intent of that, is concerned for new avenues previously unexplored, and they don't necessarily have to be offended any social cause or demand, or lack thereof.
Shocking is purely experimental, whether something tries to be shocking, or not.
