I contest the idea that Latin text can never look good on a flag. Rather I think that these West Asian flags look like flags worth dying under... precisely because they literally are flags that people are currently dying under. Which is to say that these flags come from a culture of active and organized armed resistance against colonialism and imperialism, whereas logos like PVDA/PTB's or Norway's Red Party's are instead designed inside a broader culture of entrenched liberal democracy. The logos of major leftist parties within the imperial core are meant to compete with the logos of (other) parliamentary parties on election posters, which means that how good they look in videos of people with guns is just a complete non-factor as long as there are no people with guns in the picture.
