If someone proposed the banning of rent supplement recipients from your apartment complex, would you vote for the proposal at the AGM?
On balance I think I would.
All of the antisocial behaviour in our complex has been caused by rent supplement recipients. That's not tarring all rent supplement recipients with the same brush...obviously not all are troublemakers. But there's obviously a higher concentration of troublemakers among rent supplement recipients. It'd be easier in the long run just to ban them all. The logic's similar to that of countries such as the US that ban individuals with criminal records. Most will probably never reoffend but why take the chance?
Eh, all anti-social behaviour to date, and if you ban them all you are tarring all them with the same brush.
By your logic, as blacks form a larger proportion of the US prison population, it would be acceptable to ban blacks too.
Address the issue by dealing with the offending individuals, and not singling out a particular group carte blanche. I don't think you or anyone would think it fair to be judged on this basis.
