You are not alone, sir. All of us felt that.
Some left. Some channeled their anger in different ways. Some do it with expletives, Some like myself do it with the occasional jokes and sarcasm.
I was never too much into the military stuff but I too developed a noticeable disinterest after the events of last year. In fact, I think my second post was about how I was no longer interested in military stuff. Very polite and honest post. It got promptly deleted by some mod.
My first post was on your thread you created to protest good economic news that Bangladeshis kept posting without mentioning the country in the title, leading to much consternation for us Pakistanis. That thread hit close to home and I joined after lurking for 4 years. So thank you.
Please keep contributing from time to time. I know it seems hopeless but it's better to vent it than keep it inside.
