The BIG difference I see in charity, is that Christian charity groups help EVERYONE, while Muslim groups seek to help only other Muslims.
Given that the Quoran encourages the Muslims to be generous in helping others, in practice they are perhaps the most inhospitable people on earth. With wealth beyond measure under their feet, these entire nations are world leaders in famine, disease, poverty and illiteracy.
Are all muslims our enemy? No, I don't think so; but they aren't our friends either. They are our allies, as long as it suits their short term agenda.
To think otherwise is hazardous to your health.
