Brave move by the coalition, the statements should be backed up by the LET/EJ, what have they to lose if they're banned already?
Unfortunately, I don't think the messages will reach all supporters, and some who see them will ignore them. The attendances may be somewhat lower than usual but will go unnoticed in the grand scheme of things (weather, time of year, form etc) and it will be the regime blaming the fans once again, divide and conquer.
I really hope the boycotts work and we get massive media coverage about this, sadly I don't think we will.
