Don’t tolerate difference. Tolerance is not enough; you tolerate something you don’t like, but can’t be bothered to try to change.
Accept difference. Embrace how people differ from you, differ from your expectations, and differ from what you are conditioned to believe people should look like, act like, live like, and be like.
Difference is not to be feared; it is to be celebrated. Allow your self the power to accept someone other people don’t. It takes far more strength of character to accept people who fall outside your social expectations than it does to tolerate or fear them.
Let them be and express themselves without having to explain and defend themselves.
