They did achieve something. They brought everyone attention to the dismal situation at Villa and the club was sold shortly after. FWIW I do think the protests helped with the sale. But in the post I was picked up on I wasn't saying that. I was pointing out that Villa was indeed sold after the protests.Are you sure? Your reply of "What about the Murray out ones? Or the ones at Villa?" to @samaistonsrightfoot stating "Protests do fuck all" seems to imply that the Villa protests achieved something.
