Many of these obnoxious twat that comment on subject on which they are profoundly ignorant couldn't find their own arse with both hands and a detailed map.
This really comes out when left-leaning soft-shells start commenting on military matters.
After what is usually an anti-american/anti Israeli attack, they wait until somebody who actually had a clue replies and start slandering them with cries of 'armchair general' or 'chickenhawk'.
Then if the person attacked responds with some credentials they are told that they are:
- Plain lying
- Not for real as real servicemen won't talk about their experiences. (Hmmm-So where did all those NON_FICTION books on war come from...)
Ain't the interweb great!
Try THAT mano-a-mano in the real world where you might have to back up the lies and slander.
