For me, personally, Decolonization is reclaiming my own culture. I believe that decolonization for nonnative folks is to begin the journey of reclaiming their cultures.
This can be difficult since a lot of people are mixed with many cultures but your blood memory will speak to you. Find the ancestors of your past that speak to your soul and start from there.
Decolonization is not about appropriating Indigenous cultures if you are not Indigenous but rather learning about and honoring what you learn.
The work that you put into dismantling the systems of oppression is honoring the peoples you have learned about.
