I think it is just that now we have options.
You got venues, gigs, distributors and publishers where you may minimize certain offenses.
If you are looking for that type of stuff that the category above wants to avoid, you still have the other places, labels, distributors and so on.
If you want to just do whatever, with whoever, I don't see much obstacles in that either. I belong to this last category and I rarely encounter any problems anywhere. And if such ones emerge, its fine, since I am not after the safe space. I think "noise" is not one space, nor community. You can't regulate it, as there aren't really means to regulate things. Generally when such situation is valued, it might give indication of healthy "scene".
