So, what was the insult to the family?
Are you suggesting Obama was there for every dead soldier returned home, or is your belief in Obama founded in fact not fiction? Since we know Obama wasn't there for all of them, can we assume you were as upset with him for the times he wasn't there?
It actually is disrespectful to kneel. He actually did write the letters (unless, of course, you can prove the negative that he has not). He explained why he hasn't called yet. My priorities are fine - as you suggest, one can have more than a single thought at a time (well, I can, I'm not sure you can).
I've also said that I think Trump was wrong in this. What is it you need me to say? Are you just fighting to fight?
