You won't be able to fix a troll who obviously has his mind made up about a group of a billion and a half or so people.
You'll have all kinds of facts and figures, you'll have everything credible under the son, and still will not be able to make any headway.
People don't come in here to discuss and maybe even learn from counterpoints. People like that don't want to listen, they only want to regurgitate (I like that word). They are the type of people, whom if you're lucky, may let you finish talking --- only for them to have the next opportunity to talk.
You've been lumped with the liberals already...in that man's book..
You have a story and it includes honorable service.
You have a point of view based on your life and your experiences.
Sadly, this man, even if he chooses to have his story, chooses to let his point of view be written for him...
I could totally school him on the topic as well, but what does it matter? Do I want to put full-on energy in trying to educate someone who already can't think for oneself?
Not worth it. You've been lumped, I've been lumped in a box and in his head that can't be changed.
