Some of them adopted american values. The problem isn't mexicans. It isn't immigrants either. It's morons. The problem usually lay with the sheeple. Yeah it's easy to see hey look, they ran away from their shithole and instead of adopting the values that make America great, they keep the value systems that made their country so terrible they fled here. But you can see this same problem with the leftist that flee their cities and make the suburbs shit, or the leftist that flee their blue state and drag down the other states. It's not mexicans dude, it's the fucking idiots that don't realize their own culture and ideologies are fucking garbage.
