I agree with many of the sentiments here. They are just thugs doing what thugs do. The vote was nothing more than an excuse to have their fun.
There were thugs there on both sides. Yes supporters going down specifically to cause trouble at the No celebrations, giving the thugs on the No side an outlet to channel their thuggery to. Otherwise why else would they be in attendance at a Pro Union rally? Especially after having the square for the previous couple nights to celebrate their pro independence stance (where there were reports of Union Flags also being burned).
Responsibility lies on both sides. No need to kid yourselves about this. And after the weekend, these thugs will get back to channelling their hatred through the normal channels. Football. They (both sides) must have taken it tough with Rangers having to work their way back up the ranks, there has been little in the way of Old Firm thuggery for a while.
