Well, holding up a flag makes a statement. That's better than nothing. I guess your participation,Bob in the past may have resulted in no change for the cause you were protesting for.
Those who protested against Thaksin eventually encouraged the generals that there was some support form the people here for stopping him. I'm not saying all people would support a coup but the generals could see that a lot of people hated Thaksin too.
Protesting can cause change at times. Opinions get heard. Sometimes that's the only time they get heard.
I'm not saying I am going to get involved because to be honest I am just a lazy f0ck. There are those who talk and those who do. Most of the time I am just talk the talk.
