Scientific studies point to racing at 2 being better for soundness. If you responsibly exert stress on the bones of a 2yo, their skeletal system will ultimately be stronger for the weight that's likely to come as they grow. Now obviously you can't over-train/race them or that'll do more harm than good, but if they go without that stress, you can end up with a frame that's possibly under-prepared to handle the weight of a maturing horse. If the 2yo is already massive and gangly, there'd be some adjustment to the idea of responsible stressing of the bones because you're already dealing with a lot of weight on an immature frame.
People get emotional about the idea of protecting the poor babies, but it's not based on fact, just feeling. Surely they'd be better off waiting, etc. Not really. If you want a safer situation for horses, bone strength matters and you're more likely to get that racing at 2.
