I have to wonder why I see posts like yours ("What you guys do is worthless") on a pretty regular basis and I never see posts asking "So, do you guys know of any effect these demonstrations have?" or "I used to do these demonstrations, but after finding that they had no effect I stopped, so you should, too."
In other words, it appears that those on FR who criticize we street Freeper types are folk who have no idea what they're talking about, but consider themselves experts all the same. And not only experts, but experts who feel like they're qualified to tell the rest of us what to do with our Friday nights and Saturday afternoons. That's not arrogant at all...
I've had military members and their families thank me for what I do, and have had the honor of being thanked for it personally by WWII veteran, including a Pearl Harbor survivor and one guy who wrote to the newspaper to thank us just weeks before his death. I've also been thanked by Vietnam vets and have been joined by them on my corner and asked to march with them in the Memorial Day parade on the basis of my troop support work alone. No veteran or family member has ever told me what I do is a waste of time. I'll take their judgement over yours, thanks.
What Mr. Silverback wrote goes double for me.
