I wasn't being any more a jerk about it than you were with your original message.
Where was I being a jerk in it?

It was mainly a suggestion.
^I'll stop discussing that here since it's apparently a problem.
People get pretty hypersensitive about this stuff. I wonder if it would become an issue of race if they all of a sudden decided to add a black soldier, an ageist issue if they added a character who saw too many moons, or a lookism if the soldier was super ugly.
Although you couldn't pick them there has been a black soldier (voiced by Ice Cube) and an older soldier, probably not as old as you're thinking. With how graphics work for the games I'm sure there have been ugly soldiers too.
