I’d assume that any news that is to the right of “left of center” doesn’t get much visibility on Lemmy. Maybe Lemmygrad or Exploding Heads are a different story, but I figure they’d sooner ban the bot in far-right communities than let it highlight biases.
My gut had me wanting to say the same thing, but looking at the age ranges, this actually seems reasonable and in line with how many other countries operate. By 6 years old, students in the US are in first grade, for example. Kindergarten a year or two prior as well, which is also compulsory in some states.
