Is a relationship between cousins considered incest?

In my culture, cousins can get married, they are not like siblings, and they are not close like siblings, my grandparents are cousins, i said that to someone on the internet, and they said that it's disgusting, i don't really understand, it's okay for one billion and half of the world population, but not for the rest it's not, I think it's a relative concept among people; cousins are viewed differently due to cultural differences, so you shouldn't think it's disgusting, I believe . I mean you see your cousin as your brother but i don't even remember my cousins names , i meet them at weddings , they have a sick mindset so i don't like them,but if someone from my culture saw his cousin this way , it's not wrong
