As the title says.
Hashi-nashi zoku is a Japanese term describing a person who cannot use chopsticks. It was primarily targeted at foreign tourists from the West who cannot use chopsticks. But as the western foods become as familiar on Asians' dining tables as they are in the West, more and more people are not going (or barely) to use the chopsticks for meals.
Personally, I can use chopsticks, because of the Eastern culture. I can even use chopsticks on some Western foods (it's hilarious to do that). So, I'm not a Hashi-nashi Zoku.
