Well I guess the response posts pretty much sum up the mentality of "service to others" which exemplify the center of every Marine's personal core values. This isn't to single you out, merely to get your attention in case you're ducking the thread you started. Welcome to our world where we hold ourselves and those thinking of joining our ranks to high standards.
Unless you're totally committed to earning the Title of United States Marine and serving wherever the Corps sends you without thinking about what you'll get out of it, you'll be one of the one third who wash out of our boot camp. It's the way our system is designed.
The reason you're really drawing so much grief here? Many Marines die keeping our code of ethics which is to save the lives of our fellow Marines even if it costs us our own. It's not that anyone is trying to be a hero, far from it. It's simply we care as much about each other as we care about ourselves. It's just our chosen way as human beings.
If you reread what you wrote now that you're beginning to understand us, you'll see why so many are angry with you. We've lost good friends during bad times in hard places and we live with these painful loses the rest of our lives.
Be mindful of what you say to others as you never know ...
An apology is always a good start to reopen communication with people you've disrespected. Even though you didn't mean to, the deed is done so it's time to step up. Builds character and for what it's worth, we Marines admire it because we never ask anyone else to do what we wouldn't do ourselves because that's a failure to be a good Maine in our playbook.
