> We have solid data that building transit lines actually decreases crime.
Do we? A cursory Google search revealed a couple of papers, one of which showed a slight increase in crime after the addition of a bus line[0] in Cleveland, and another which showed a decrease in homicides but an increase in property crime[1] in São Paolo. I'm not cherry-picking; these were the first two PDFs in the search results. I would love to see the evidence that you presented to your friend's dad.
> If you talk to them for just a few seconds it becomes readily apparent the root is just straight up racism, but they don't wanna own it overtly.
This may very well be the case as you exhort downthread, but I just want to point out that besides the obvious (that we are all internet randos who don't know your friend's dad), racism means different things to different people. I know people who think that if a white author writes nonwhite characters, it's racism. I also know people who were disowned for marrying "outside the race". My personal definition of racism is a lot closer to the latter.
Sometimes a concern for crime is just that; other times it can be a code for a race-related pretext. Here's a thought: if you're concerned about female genital mutilation, which is virtually only practiced in sub-Saharan Africa, the Middle East, and the Muslim countries of South Asia, are you concerned about the women being mutilated, or are you just a racist?
