You may have read that as immortal. No, Democrats don't think that they'll live forever. People assume that since you're a Democrat that you must be some heathen that has open sex and does drugs. First off, who cares if that is what I do? Secondly, no. I could even be so liberal that I think sex work shouldn't be illegal. That doesn't mean I want to go out and do it. Just because a Democrat wants the decriminalization of weed doesn't mean they are a huge stoner. Again, even if they were, who cares?
A lot of Republicanism stems in being religious, which there should be a separation of in our government. This is not a Christian nation. There are Christians here, and bless them, but we don't live under Christian rule. Look it up.
