You should try to get more people on the path of enlightenment. They will be better it off. My new journey on path of enlightenment has help feel better about myself. However, don't cram it down there throat like the religious fools due with there fairy tales,etc.

Live and let live. Be yourself and don't make apologies. Teach tolerance but don't preach about it,

I think the fight is not with the individual but with the town/state/region/country to create a better educated and PROPERLY informed populace. I don't really care if you believe in god, I do care if you don't believe in climate change and a myriad of other things because you're stupid.

No one care what you or I think just as we don't care what others think. So I would keep it to myself.

I only give my opinions when they are warranted. When someone engages me directly, or when I see something I want to respond to on a public forum. In person I am less likely to do it. I go out to have fun, not argue with people. Don't harm me and I won't harm you. Even when I do give my opinion it's to just get it off my chest and/or point out the truth or what I think is true, or if I feel someone is wrong or being deliberately obtuse. It's basically a form of entertainment and/or catharsis. I don't really care to change their opinions because it's almost entirely futile.

I don't like to have someone proselytize at me, and I don't do it to others. Unless someone directly asks or makes a comment I consider so stupid I have to respond, I keep my lack of belief to myself.

Beliefs are individual no one should ever try to persuade another we all find what we need to get by no one else truly knows what that is only you know what works for you

Necessary? I think it is inevitable. People's beliefs are not materialized from thin air; they are injected and influenced by those around them. If so, it is better to attempt to propagate benign beliefs and to reduce the malign ones (for example, racist or misogynist beliefs). There are smart ways of doing it and dumb ways of doing it. I think the question is not whether, but how.
