What was she doing there while her husband was speaking? Was she just a prop?
What did THEY sacrifice? NOTHING. Their adult son voluntarily entered the military service, and from all indications served honorably and died a hero. That was HIM. There is no indication anywhere that they encouraged him to pursue a military career, or had anything to do with that choice.
To "sacrifice" means to voluntarily give something up. They are bereaved, they had the worst experience any parent can have, but they sacrificed nothing, and deserve only minimal, secondary credit for their son's service, unless they can show that they encouraged or actively supported his decision.
And they had NO JUSTIFICATION whatsoever for their vicious, personal attack on Donald Trump, a person whom neither of them had ever met. And their "reactionary" diatribe was TOTALLY UNJUSTIFIED, either personally or politically.
Trump NEVER SAID ANYTHING AGAINST MUSLIMS LIVING LEGALLY IN THE U.S., and he never said or implied that a Muslim is any less worthy a citizen or incapable of being a Patriot. NEVER. Thus, they were reacting to things that Trump never said.
Trump has suggested that the U.S. impose a TEMPORARY MORATORIUM ON IMMIGRATION from hotbeds of Islamic extremism and terrorism - something that the vast majority of REAL AMERICANS agree with, enthusiastically.
Trump has pointed out that 90% of the terrorism in the world is motivated - legitimately or otherwise - by Islamic fanaticism.
TRUE!
Trump's "crime" in all of this is that he was inarticulate. Contrast this with Barry and Hillary: articulate liars. I'll take Trump over them, any day.
