This probably futile, but...
How are longs any different? If I buy a share of Apple tomorrow and go long, my bid will have some microscopic effect on the share price (or "opinion"), I will have contributed nothing of value to the Company, and I will absolutely be trying to make money off the labor of others. Aren't we all really playing the same game? How can I be good when I'm long, and evil when I'm short?
Being long is actually investing. Shorting and option trading is more akin to gambling. You are not actually investing in any company.
