A man expressed admiration for and gratitude to the United States military in general and the United States Marine Corps (of which you claim to be a member) in particular ... and you deride him as an "ungrateful turd".
Your behaviour is disgraceful. Your disgraceful behaviour reflects badly upon the Marine Corps.
Frankly, sir, you disgust me.
Good day.
Bwahaaaahhaaaahaaaaaaaaahaaaaaaaaaaaaaaa
Agree!
What was it that Major Payne (in the movie) used to say . . . something about his Agent Orange acting up?
My guess is the person is a troll.
