You're a theist against immigration?

[Angrboda]

All humans are mere dust particles shaped in the picture of a man or woman. There is no difference between White, Black, Hispanic or Asian, these races exist so we know and recognize each other only, closing borders and building walls is just the destruction of this natural, beautiful human fact: we are a specie of different faiths and different practices, we should believe in what we want, and let others believe in what they want.

From Islam, this is the verse that I see most suitable for this:

https://quran.com/49/13?translations=

Sura 49, The Quran:
Sahih International

(13) O mankind, indeed We have created you from male and female and made you peoples and tribes that you may know one another. Indeed, the most noble of you in the sight of Allah is the most righteous of you. Indeed, Allah is Knowing and Acquainted.

We are all brothers and sisters in race. Color is only there so we know one another. Human is the password, and borders must be opened.

Have you informed your government of this?
