I'm fairly sure this is an adult. The key is the uniformity of the individual letters, even the "scrunched" letters where the words close up against the right hand margin. The only errors ('dieing', the misplaced comma) seem contrived - if a child can correctly spell "soldier" he shouldn't have a problem with "dying", and he certainly shouldn't put his comma in the wrong place in the salutation.

Somebody who is trying to write like a child contrives obvious errors but overlooks the "automatic" stuff like letter formation and correctly doing more difficult tasks than the ones deliberately botched.

My money's on one of those liberal loonies that hang around outside Walter Reed oozing hate.

This is a death threat. If it's a kid who wrote it, they need to be told why it's wrong. If it's an adult, send them to jail.

The writer has already been exposed. The twerp is a Ted Rall wannabe. Turns out the twerp also has white supremacist ties.
