I don't understand. If your grandparents changed the language they speak, why did you also have to do it? Or did you change it to something else again?
Yep. They came from Germany to America, and switched to English. I came from America to Québec, and switched to French. My wife came from Jordan to Québec...and so forth. We knew we were moving to a French-speaking place when we came, so it didn't feel like much of an imposition. And both of us were rather thrilled to move somewhere more secular than whence we came.
Anyway, the point is, of course, is that religion is a "choice" like consumerism is a choice, like language is a choice, like capitalism is a choice. They are not circumscribed objects which come to us unencumbered. They come with programming which runs deep, and not only, in the case of religion, identifiable as this or that ritualistic practice. Likewise, this or that ritualistic practice has dimensions which far exceed the act itself -- they have deep-seated ties to relationships, indentity, belonging and so on. Not something you can just easily "choose" not to have.
I was on the board of an atheists' group in Tennessee. Every last member had grown up religious initially. It's not easy, any more than learning a new language is easy, but it's a lot easier than changing your skin colour. And I'm not actually calling for anyone to give up their religion over this extremely silly dispute (which has now been rectified). I was just saying it was religion preventing them from playing. And now it won't anymore.
