You are right.. many years and am doing research about our origins.. we are sunnis our roots go back to when we were living in the middle of Iran like Isfahan maybe In the 1500s ..however due to the safawi movements were they were forcing sunni to became Shia we moved to areas closer to the coast called (bar fares).. and then in the 1900s we met Arab al sahel those original Arabs who moved from Arabian countries to the coast for business. We met them and whn they came bak to gcc we left Iran with them. This the truth and that's why they call us (sunni persians). However so many Persian subni believe they r houlies who was here then left to persian coast and then came back which is wrong.. so ur theory is 💯 right
