No, it lists a whole bunch of sins, homosexuality amongst them, and says they are worthy of death. It does not say kill them for doing so. Anyone advocating killing anyone for sinning isn't practicing Christianity. Now that does differ from the state performing executions for certain crimes. And it differs from self defense. But with Christianity we are no longer under the Old Testament Law of Moses, called the law of sin and death. We have freedom in Christ. But that freedom doesn't allow us to do whatever we like without consequences. Ultimately we are judged on how we live.
