Everybody knows by now that if you stand up you run the risk of getting lifted.
I was always against the all-seated stadia and no-standing regulations, and would welcome back a section of terracing. However, I also know that until that happens, I stand at my own risk. I don't condone any heavy handed tactics by the stewards or the polis. If that happens a formal complaint should be made to the club and the authorities.
It seems like every other week, however, that people are posting how surprised they are someone got chucked out for standing. If you want to try and change things, there are more constructive (and likely more successful) ways to tackle it.
