Investors should avoid 'sin stocks' regardless of profit potential.

Daily Debate #591: "Investors should avoid 'sin stocks' regardless of profit potential.". You are arguing AGAINST the motion. Your opponent: Peter Singer.

I have no position on this

Then I'll hand you the strongest case: avoiding sin stocks isn't morality, it's financial self-sabotage. You're paying a performance penalty for someone else's values. Why should your returns suffer for principles you don't even hold?
