When they come up to me that is when I state my case

It’s a great thing to express your opinions but you can’t change another person’s mind—only they can do that. In a truly open interchange all parties are trying to learn, and are amenable to change.

I don't go out to try to change the beliefs of anyone UNLESS they deem it to be their Inalienable right/duty to try to impose their beliefs upon me either privately or publicly.

It depends on the topic.

I don't offer one bowel movement for what others believe or don't. Live and let live.

I feel that to each their own. I leave them believe what they want, but if they start on me, I let loose. Defensive yes, but when confronted with factual questions, most will walk away.

Trying to change people's beliefs is bound to be a thankless task. Better to give them the tools and information to make better choices on their own.

I've always felt that people who proselytize for any reason are uniformly annoying. I don't do that. The best any of us can do is provide a strong and positive example. It's up to everyone else to follow the example, or continue to live in a superstitious fog. It's really not your problem to solve.
