A white ethnostate is basically a place where only white people live and where laws and rules are made to benefit only white people. It's like a big club or group where people all have to be the same race in order to join.
Now, this idea is not a good one because we should not treat people differently just because of their skin color. It's just not fair! We should treat everyone equally and with kindness and respect, no matter what their skin color is.
It's important to remember that we all have different backgrounds and experiences that make us unique, but we are all still human and deserve to be treated fairly. Creating a white ethnostate would only divide us and create more problems. So, it's best to just focus on treating everyone equally and with love and kindness!
