And since you had this in there (Which means that Democrats generally like blue city policies, on the whole.) one can conclude that democrats are in fact fans of crime.

Not at all. This is a mistake commonly made in politics - when someone supports a policy, one claims that they support even the unintended or even negative outcomes of the policy. For example, stricter enforcement of Medicaid qualification documentation has the consequence that some people who are eligible for Medicaid won't get it. That doesn't mean people who advocate those rules are fans of denying people Medicaid who deserve to get it. It just means they think the benefits outweigh the negative consequences.

I think you would vigorously object if someone claimed that you supported the adverse or unintended consequence of every policy you supported. You would insist - correctly - that one can support a policy that has both good and bad consequences (as all policies on complicated matters do) without actually desiring the bad consequences. It would be courteous to extend that same expectation to your opponents as well. It would also help you actually understand what it is they believe....
