Socialism,
I see nothing in her comment that would lead me to believe she is a Christian. Compassion is a universal "trait" and I agree with her regarding that compassion doesn't mean enabling and supporting bad behavior. I think it means that despite someone's bad behavior you still look upon them as human beings who have made bad choices and who may be trapped in a dark pit of hopelessness. Some of those folks have mental illness conditions that need medication and treatment as well as advocacy and assistance in getting a place to live. 
Some of those have given up on themselves and no longer consider themselves as part of the human race. Some are prisoners of the addictions they became hooked on. Not sure how to escape. Some are folks who have been born with organic brain damage and some are folks who received injuries that resulted in brain damage.
But, if she is a Christian, so what ? Even they have a right to thoughts and opinions that don't fit in your preconceived ideas or box.
