I have no horse in this race but there's no need to lie. Let the truth be enough.
1) That's a boy, not a man.
2) He told you it's a declaration of faith, not "jihad". I believe that flag is the "shahada".

If we are to condemn the other side when they do this, then you shouldn't do it yourself.
Do better.
