You and I both know there is the same concentration of white Mormon families in Mesa as anywhere in Utah. To say anything else just means you're dilusional.
Are you being serious there? While there are a lot of Mormons in the Mesa area, the concentration isn't remotely the same. As I posted below, it was 15% LDS in Mesa back when I lived there in the mid 80's. It's around 6% right now according to this link:

Utah County is around 80% LDS (according to census figures reported in the SL Trib) whereas SL County is about 51%.

Demographics have also changed quite a bit since then, with an influx of non-LDS people from other areas. The latin population in Mesa itself has gone up significantly. So, you're either trolling, or it's actually YOU that is the delusional one.
