Have to agree. I think I'd remember exactly how many times a knife had been pulled on me. For future reference, and to assuage your curiosity, twice.
Great example, but I wouldn't evict the likes of the Ardoyne rioters because of just their behaviour to people walking past them. Like I said it is a multitude of offences.
It doesn't matter what I think. i am not going to be able to change people's minds on their prejudices but i can successfully mount an argument to challenge the circus around those prejudices.
