Ok so you admit you have heard some of their music just not all of it why can’t you give an opinion on what you heard even if you only heard one song you should be able to say you liked it or you didn’t.
Or when you say you knew some things you’re saying you have never heard any of their music and just knew the names of the songs and generally what they were about or was it that Tom Morello wrote an article where he gives a negative opinion about someone you see as a rival for your preferred candidate?
I’m beginning to suspect that your definition of wisdom is ignorance of facts that run counter to your ideology.
