I am writing this because I am curious about Democratic Party supporters

When I look at the Democratic Party fandom..
I have seen them attack opponents using things like their gestures or the food they eat.
For example, when Yoon Suk-yeol eats jajangmyeon, they call him "Yoon Jjajang,"
or when Lee Jin-sook ate bread, they called her "Bread Jin-sook," and so on.
Are Democratic Party fans..
a group of hungry people or poor people?
Is that why they have a grudge regarding food and attack opponents through it?
On the other hand, I have never once seen
People supporting the People Power Party attack the Democratic Party based on the food they eat.
Are Democratic Party supporters really hungry people?
