Sourdough,I like to keep an open mind and be able to deal with people on a factual level. But when you're collecting songs from someone who is generously giving of their time, I think it's important to get away from ideological disputes and keep focussed on the project at hand.
Most ideological discussions don't seem to change anyone's minds about things and there is always an appropriate form for this. Somewhere along the line, it's important to get past ideological differences and bridge the gap with that upon which you can agree.
Love of music is pretty much an agreement.
