well if this world is so horrible, why don´t you take a speedy exit then ? I saw couple of your posts and all you do is dig out outlandish examples up to the extreme. if you live in such a crap sack world where your life is cheap, you are either tough as nails or simply good at telling stories. I personally tend towards the latter.
but yeah, since I lack data of whatever you say may be true nor not, I can tell you however that gratitude always fall short of genuine appreciation. In case you don´t know in most western countries people take on oath to serve their fellow man in HIS glory. So yeah, they are doing it by proxy and if you proclaim that they are violent, rude or unreliable, that is a public stance against the Lords servants.
I appreciate a man who will risk his body and life to save others any time. Be they veteran and old or young serving as the police or a fire fighter or an EMT, they will be worth talking to.
This may not be soft or cushy the way I wrote it and it is not meant to be, I just simply think dismissing serving people and generalizing your bad experience for a phrase is nothing to be taken lightly.
