what is wrong with iranians becoming the hegemon? they were at the top of the islamic leaderboard during the islamic golden age. almost all of the scholars and scientists came from persian stock. the only other option is letting turks rule again. if anything arabs seem to be incompetent to me. the fact islam at its peak was best when non arabs ruled the islamic world is actually kinda funny. so what if iranians are committing shirk and innovation with the faith? after 100-200 years islam will go through another revival just like always. better to just give up this pointless fight when arabs cant do anything right.
