If Christianity and Islam for whatever reason go to war with each other again one day, which side would YOU be willing to fight for?

Do atheists and Buddhists and Hindus and Jains and Sikhs etc have to pick a side? Can they not stay neutral and not get involved?

I would copy Barack Hussein Obama and Donald John Trump and let the "losers" do the fighting.  

they wont... both believe in Jesus and both believe in God.. the God of Abraham... they are too common in brethren to fight.. 

Neither side is worth fighting for.  

while I'd be happy to see all  religions gradually (and peacefully) fade away , I would not welcome a global conflict involving the world's 2.5 billion various  Christians and th different versions of Islam with 1.6 billion followers. 

Neither.  I like our ancestors worship the Sun, the giver of life.
