They're awful. What they're really trying to do is intimidate, and discourage people from expressing any opinions that don't align with their own. They pretend to be all about freedom, but their notion of freedom just means you're free to agree with them or suffer the consequences. They're insecure, small-minded trolls who lack the knowledge or capability to present and defend their beliefs in a civil, respectful manner. All they can do is lash out and insult those who dare to think something different.
