Common sense says that in ANY business, it's ultimately the bottom-line and customer retention that drives the owners, in the long run.
That said; I don't care about the gender, sex life, color, origin, etc. of the employee but rather care about their work ethic, production, character, and their contribution to the success of the business. ANY other forced rules have NOTHING to do with the success of my business, unless I'm looking for government handouts/payback, which ALWAYS are going to be used as vote-buying and dependency-creation, or to fund re-election and power.
Except Air America. :-)
