It doesn't matter what you believe, as long as you believe. Even the belief that you hold no beliefs is a belief!
The only boundaries are that you do not impose your beliefs on others, and you do not harm anyone in the pursuit of your beliefs. Respect, trust, share, discuss - yes! That is the essence of our country, our freedoms - do not take them lightly, they are a privilege, and many have died or been hurt defending those rights.
It is not asking you too much to hold fast and true to your internal belief, and to exemplify those beliefs in how you actually live your life.
How do you handle people whose beliefs are different than yours?
