Labels

On way back from professorial lecture. It opened with the line 'I'm a feminist and a marxist.' Not only did it make me uncomfortable as a white, middle-class male but they also seemed a little dated as labels. That said, I couldn't as confidently label myself. And how would they feel if I said I was a male, conservative academic? It's not a popular stand in academia but it's the truth and I wonder if my work should reflect these labels?
