Excellent point. To add to previous comments as well, the early years of the colony lacked the sort of infrastructure to mitigate what disease vectors there were. Frankly the English had no frame of reference at all for life in a tropical , and then arid, environment. OTL Virginia is much closer to England in climate than ATL Virginia : P
Slavery is a economic fact of life. Colonies in Brazil, regardless of patron nation, are exploitative to the extreme. The Arabs are establishing cash crops, the Dutch are, the French / Spanish, and the English. Cotton, sugar, tobacco are, like OTL the biggest exports. Also hardwoods especially by the Arabs. Like OTL this will end up with a large slave african population in European Brazil. Distinctly unlike OTL you have a already existing, multicultural population just nearby which is going to affect things. By this point New World Arabs are a creole of Old World Arabs, Iberians (Arab or otherwise) Native Americans and small Black African, Western European and Berber populations. Arabs set the cultural cues for life in the American tropics, and as hostilities ease between the Virginia colony and its northern neighbors cultural mixing will lend a distinctly Islamic flair to rural colonial English society. Do not expect mosques to pop up in a elegant southern style across grand ol Virginia but do expect different dress, phrases, trade pidgins, intermarriage between English men and mixed-race locals, etc. Many bring their families to settle in Virginia but on the frontier it is very much a bachelors game, and as anyone who has used internet dating knows single men will consider any possibilities.
As for long-term race relations, the jury is still out on the question.
