It's really hard to explain but let's try. I belive music is the expression of the soul, it's energy so it belongs to the inner realm, i mean the feelings. Religion and politics are very important in life but not as much as the feelings because they are external factors. Music must be over good and evil, over external factors in fact, because it's one of the few things that can make feel the same emotions with independence of your race, sex, religion or political ideology, and we should preserve this. If somebody uses music to spread religious or political ideologies is prostituting such powerful, pure and neutral tool.
On the opposite i think it's really valid to use music for denouncing unfair situations but never through political or religious ideologies because who am i to instil my thougts to other people. I just can share and discuss them but nothing else. Dogma shows a critical and even ironic point of view from religion but doesn't spread any ideology and this is ok for me. Maybe i didn't expressed myself properly but this is not my language and it's hard to me communicate complex opinions. I'll take care about this.
PD: in spanish is ''silencioso bob''. I picked it because he's a freaky (and sometimes misunderstood ) metalhead.
