If you mix personal social or political opinions with music, then you lay yourself open to critical comment - and more - from audiences, club organisers, etc. You pays your money...

I have, like most of us, strong opinions on a whole range of matters, but I've never mixed those with the music I perform. (The nearest I get to social comment is "Brother, Can You Spare A Dime"). For me, music is not a political or social instrument, but for pleasure and entertainment. Just my personal choice, and good luck to those who think otherwise.
