What job is he doing by tweeting "Praise Allah"?

Is it really contrary to facts to point out that this is not normal? You started this by saying The Atlantic's headline was incorrect.

The question is what is or isn't normal, as per the headline you disagreed with.

I do believe that a sitting US President tweeting such a thing is extraordinary. And does indeed deserve some analysis for how we got here. Not like in a clickbait we are doomed way, but just a reminder of how far we have gone as a country here.
