It is undertandable, but the genre has so many different ways of expressing itself. Just like with metal, rock and punk, it depends on the mood and day what I want to listen to.
If someone is introduced to the more "trashier" version of either metal or punk and they decide it is not for them, they might be missing out on the "lighter" and nicer songs of the genre. In this thread I tried to post different types of songs, especially songs that are easier for non-punkers to listen to. Listen to crust or something might kill all interest immediately, and I completely understand that.
But I try to encourage to find new versions of the same music genre, just like with metal or rock (my expertise ends there), one might be missing out on much that they might like if they judge a genre by a few "heavy" samples!
