I know what you mean, some atheists can be weird and I definitely was when I first lost my faith. But I have grown a lot and I respect all religions. I can see the beauty in religion, I love how the festivals unite people, I love how some people find comfort in it and all of that. I don't hate religions, in fact I want to learn more about them. And yes, I know the star of David is more of a Jewish symbol. Also, I did try to make the situation better by explaining that I've taken to learn about other religions and I particularly found this David story fascinating. But that just made it worse, because one of the people told me to stop straying and remember my roots (coz she knows I used to be Christian). She sounded annoyed when she said that, so I just kept quiet after that.
