Contempt

Nominate one congressman/senator who might make a good pimple on a soldiers ass.

What? No nominees. Surely one of the hundreds could qualify as a whitehead at least. Some of them are as irritating as full grown boils. C'mon, what about the guy with 75,000 dollars in his freezer. Surely he could be an ingrown hair or something.

what's the metaphor

Apparently that hired-child killers deserve blind support in their 'mission' and the OP wants to elevate the common soldier to some kind of demigod status wherein comparatively an elected official can barely be a 'good pimple on a soldiers ass'. 

gay metaphor is gay.

Neither ass nor soldier are gender specific. It's back to sensitivity training for you, cupcake.

>>4
Elected officials who think they are demigods are betraying common soldiers doing the job they were sent to do.
