Bumper sticker critique

Today I saw a bumper sticker of the silhouette of a soldier kneeling and aiming his rifle.

To the right of that were the words, "If you can't get behind our troops, feel free to get in front of them"

To the left of this sticker was "My son is serving our country, what's yours doing?"

And finally in the bottom right was a bumper sticker showing their Christian church membership.

It's nice to see a Christian making snide jokes about people getting shot and killed by our military for possible not agreeing with his sons service.
