Tell your evangelical friends that Christians don't support murder, much less genocide. If they think its an "us vs them" thing or that Muslims are bad, tell them to leave the judgement to God. Our job isn't to fight or support anyone fighting. Being a follower of Christ is a simple formula - you seek the truth, you withhold judgement, and you be charitable and merciful. I wish so much that churches would tell you this.
Seek the truth - Jesus told you specifically to seek truth within yourself. But also, in the modern context, that means we have to oppose all censorship.
Judge not - no team mentality. "Us vs them" earns you a judgement.
Be charitable - maaaaaan do we need to improve this. Be nice. Give the benefit of the doubt. Offer help without caring about any details other than that help is needed.
Okay, enough of my own spin, look at the thingy...
