"I'm not religious, but one of my ideologies is to do unto other as you would have them do unto you."

That belief was created and pushed by religious, political, and business elites who themselves did not give equally to other people or treat them fairly. They always schemed out more for themselves. Your rule is best modified to do onto others as they would actually do onto you to the best of your knowledge. Otherwise, your rule will result in more evil happening overtime as the good people will work within the schemes created by the bad people. That's already happening.

Illustrated nicely in Hawk-Dove game:

Even includes retaliators which are relevant here.

The platinum rule, of course, is don't do unto others as you wouldn't have them do unto you.

Maybe that is too cynical, but it works well as a rule of thumb.
