Good luck with your endeavours. If anyone, of whatever colour, tries to tell you that you shouldn't be playing a particular type of music because of your ethnic background, then they are being racist, and should be ignored, however much they may try to conceal their racism behind such fatuous pc terms as "cultural appropriation". It's no different from someone telling a black person that they shouldn't be performing opera or playing in a string quartet. Music is music, and has always benefitted from cross-cultural fertilization, without which much of the music we enjoy, and which has enriched our lives, simply would not exist. Enjoy!
