They'll also point to crime rates in large cities and cherry-pick statistics that suit their arguments without doing any in depth analysis. Especially when they can parrot irresponsible politicians. They don't care that cities like Baltimore and St. Louis have it really bad right now because all they every hear about is Chicago. And as with other topics, the problematic ones will reject any new information you present that doesn't match their pre-determined conclusions.

If you try to discuss what "per-capita" means, it doesn't matter. They'll point to the fact that there were 100 murders without any regard to the fact that it may be out of a half million people or more. They won't acknowledge the different kinds of drug crimes that happen in their own towns like meth production.

The problematic people refuse to accept the fact that poor economic conditions lead to higher crime rates. They'll give the "get an education, get a better job, people flipping burgers shouldn't earn $15 / hour." arguments. They don't care because often they haven't experienced it, and even those who have lack the empathy to see that the impoverished people in the country aren't so different from the impoverished people in big cities.

I could continue this rant but I think I'll end here. I'm trying to be cautious about using the word "they" as a blanket statement. Not all people who are conservatives believe these things, but you can't deny that a fair portion do. It's hard for us all to find a common ground and speak the same language.
