Is there any rational reason they shouldn't be honored if their child is killed serving in our forces?

Yes there is.
But certain useful idiots are permanently blind to it.

We have seen many "parents" of heroes poisonously attack the military and the Republic for which it stands, and the country which shelters them.

Honor the heroes, disdain the idiots.

Not rational enough for you?
Depends on your definition of "rational"?

And most of those parents are U.S. citizens; that is where your argument fails. You are punishing a "patriotic" LPR for the "unpatriotic" act of a true citizen.
