That's not what I asked. You stated companies shouldn't do this. Just because some entities have chosen to act in a certain way doesn't mean that it is morally correct for all entities to act in that way.
Certain companies have been founded based on religious beliefs forever, that doesn't mean that it is morally correct for every company to have religious foundations. If you want to run your company that way, you're absolutely welcome to, but upon what reasoning do you claim it is wrong for me to act differently than you choose to?
If what someone does, does not actually affect a company negatively aside from a few emails or calls, I don't see why it should fire somebody. People will find someone that disagrees with them in virtually every single company.
Again, that's fine for you to act that way. But what you stated was the rule:
> You shouldn't be fired for things you do and say outside of work, period.
Which would presumably apply to all companies. Under what ethical basis is this a good rule? What if I want to fire someone for what they did outside of work? Why shouldn't I be allowed to do that? Why should your belief about how you would run your company affect how I run mine?
