I'm in
Our side doesn't have the time to protest and march because we have jobs and responsibilities. I'm too busy doing the jobs the illegal marchers won't do.
Check your title, when I first read it, it looked like you wanted to rally against support for the troops.
First suggestion, don't mix the immigration question and troop/war support.
Second, there was a time when FR could muster a large nationwide rally...we did it twice. However, much of that original infrastructure has been destroyed by infighting and petty turf wars. However, the inspiration for something this may still be here, so good luck.
