quasi: "Was Trump being sarcastic today when he referred to the Secret Service as the S.S. when saying how easily they, the National Guard, and the DC police cleared out the protesters for his photo op with a bible in front of a church?"

What President Trump Actually said:
“A walk in the park”, one said. The protesters, agitators, anarchists (ANTIFA), and others, were handled VERY easily by the Guard, D.C. Police, & S.S. GREAT JOB!"

quasi, commenting on the picture of the car: "Context matters"

Yep, context matters. And in this case it's pretty fucking clear that by "the Guard" he meant the National Guard, by "D.C. Police" he meant the Washington D.C. Police, and by "S.S." he meant the United States Secret Service.

If you're only defense is to say I sound like a raving lunatic then don't bother...all I can do is offer some advice; Social Media Less, Kayak more.
