cultural appropriation

Dear God/dess,

     So today has turned into looking at cultural appropriation.  There was a video posted on the Youtube Pagan group about White people culturally appropriating everything https://youtu.be/SpX1h_gGjfI.  That is the understanding of the video.  I do understand this.  Various new age and pagans do this. It is very well known and obvious.
      Now what I do not agree that people can only work with gods and goddesses from their ancestors pantheon.  This is very limiting of a philosophy for me.  I have always had a connection with ancient Egyptian mythology, the Greek and Roman and the Nordic pantheons.  I have Swedish heritage.  My mother's mom's side is Czech.  Long line of ceremonial magicians from grandma.  Mom's father was adopted so we don't know what that quarter is.  I am learning more about the Nordic pantheon.  I am learning more Thor because he has been showing up.
     Are their people that do this because it is "trendy". Yes.  I happen to be a person that loves to research and learn.  If I was called by any god or goddess, I would research the HELL out of them.  I would be open to learning about them and the customs.  My issue with the video was that it put up unneeded separation.  Especially for someone who is gender queer and attempting to remove separation and obstacles in other areas.
     So tonight I am asking you if you can show me.  Is it ok?  Where is there a crossing of the line?  I need a lesson or an illustration about this.

thanks,
John
