Idk about “leftist” as it’s outside of the Western framework but Shahid Bolsen’s rants/lectures are very informative and revitalising! He’s a loud spoken anti-imperialist political analyst like many others, the difference being that he takes God into account in his analysis. Just don’t look too deep into his past and certainly take any video regarding the UAE with a grain of salt, lol, as he might be a bit biased (compromised might be a better word, but nobody’s perfect 🤷).

You can find him on YT, the channel’s called “Middle Nation”.
