Nothing you have posted has changed this
The position you've taken that indicates that Darwin was correct was that you'd rather die yourself that kill 49 innocents in pursuit of killing one of the enemy. You, yourself, agree that your stand on this point is indeed evidence that Darwin was right.
Was there anything else, or were you going to just continue to submit posts that do nothing to invalidate the assertions, above?
Additionally if you admit you're ill suited to be in the military (whatever that means as there are many reasons people are ill suited for service including being a convicted felon, asthmatic, incapable of meeting the standards, uneducated, etc.) and claim "religious convictions and morals" this in no way places you on higher ground but reads as if you're trying to position yourself there.
Yes, you are welcome to and I support your right to express your opinion. Even at the expense of offending others but remember those who have and are serving have done so to guarantee your right to do so. .
You also couldn't resist that last line of BS. "That marine who killed 49 civilians and 1 insurgent was ensuring my right to speak!"
