My filters only come off if the subject is broached by the other person and they wish to confront or challenge me. If asked why I don't believe in god, the common response about there being no evidence, while true, seems to me a bit lacking in teeth. If I really want to lay it on thick, my response might be, "How does an intelligent, literate person in 2019 still believe in primitive fairy tales..." Another favorite is pointing out that they are almost as much of an Atheist as me because they don't believe in the thousands of other gods man has concocted.

I went through the same thing. Trust me, let it go. Vent here or to a therapist, but let it go. Especially if your relationship is great aside from this key issue.

Mine ended with a divorce (we're best friends still, and I've since curbed mine to vent elsewhere).

Hmm, in the pleasant warmth of 26°C indoors your photo is invitingly inticing for a swim. In reality I suspect that I need another 10 degrees of ambient temperature.

I would say she's the one who's right between the two of you. If you insult religion, you are insulting the victims/believers. What is religion without the people practicing it? Religion isn't some separate entity floating around outside the body of believers.

I would suggest trying harder to see things from her point of view. There's nothing wrong with speaking your mind, per se, but it can be extremely hurtful if your mind is filled with negativity. Change your thought processes and be more understanding and you can have the best of both worlds. You can shoot off your mouth without being offensive or hurtful toward her.

what does the mountain lake photo have to do with anything?

People who coddle believers are enabling rapist priests and thumpers driving gay teens to suicide. ...millions of baby boys are tortured by amputated prepuce flesh 4 square inches and a billion girls have had dirty knives slice off clitoral flesh and labia sewn up with catgut stiches since Mohammed raped a 9 year old on her wedding night.....terrorizing children with hell threats nor bribing them with fake after lives POST MORTEM
....CURBING Atheism is tacit lies for genocidal pornographic misogynistic pro violent abortion bibles 2nd Kings 8:12 "rip open the bellies of pregnant women let not anyone live BUT KEEP THE VIRGINS FOR YOURSELVES TO RAPE LATER"

It is understandable that to her she is reminded of her past, which she likely feels insecure about. Let her know it is not her fault the way the world is, and that she does not have to feel alone. We've been there. It isn't easy.

The insult was religion all along. It is an insult on humanity. But if we ignore its persistence, it seeps back into our thinking through cultural paradigms.

Then on the other hand, what difference will your opinion make in ten-thousand years from now? It is not always necessary in the grand scheme of things.
