Here in the American South, eating pizza, hot dogs, hamburgers, BBQ, fried chicken, French fries, fried fish, bread, and some vegetables with your hands is normal.
Since a lot of Southeast Asians got resettled in my area after Vietnam, you sometimes see people using chopsticks, but that seems to be fading as the older generations die out. Many restaurants still provide them, but you have to ask. I have attracted stares when eating spaghetti with chopsticks.
