Is it really? I don't know about you, but I'm pretty certain that any employer I've ever had would be severely unhappy if, on the same day of the event and before any retaliation, I've retweeted a picture of me with a flag of a country whose de facto government has just massacred 300 innocent people at a music festival, let alone the other atrocities that day. Regardless of his intentions or your view of the situation (those are different discussions), the optics are not good. And, then his next comment being "to the river and the sea...". So no, I can see how it can be interpreted as such. I never said this was my interpretation, but one that I can definitely see.
