Several reasons. First, humans have already decided that intentionally causing harm is not something we condone as a society, even under the guise of cultural or religious exemption. Largely, because it assumes that every single person part of the religion is there voluntarily, which is demonstrably false.
Secondly, it DOES affect me. There is an active effort to erode the separation of church and state, meaning Christian values are being actively imposed on those who do not claim any affiliation with Christianity. Southern Baptist, being the largest denomination in the south, is increasingly active in politics.
And lastly, I 100% agree that people within a religion should make absolutely no attempt to control the lives of those NOT within their religion. But that is not what we see.
Why did you feel the need to make that comparison? Did anyone here mention supporting their actions? Is the strawman fighting back?
