A - I said the general population may and most likely will not be a fan of the changes, just because everyone is not in agreeance with you doesn't mean your opinion is the only valid one. I'd suggest keeping an open mind, its unhealthy to have a focused tunnel vision of reality. You don't need to shape anyone elses comments to fit your own narrative. People will have some push back on a name change because of the reasons I outlined.
B - I'm keeping it very simple... the current Winnipeg downtown is dead and the publics opinion is that it's very unsafe. How do you make it safe... you need to clean it up. You can't have homeless shelters and/or safe injection sites in an area that you want an average citizen to visit. This is reality and not an opinion.
AA for drugs is a rehab facility. In a perfect world everyone could go to rehab and hope to get clean, unfortunately the city and province do not have the money to fund this. Also it would be "unethical" to force someone to go to rehab to get clean.
