To be fair he created a few PoC children in his Uncanny run. His X-men trainees included Goldballs (latino), Triage (black), Hijack (asian), not to menion Morph (LGBT) and Iceman in ANX
Bendis didnt write the X-books until years after HoM. The actual event was a decent read. I thought his Uncanny and All New X-men were both good books. Uncanny got boring towards the end with that Malloy arc but I blame editorial and the mess they made derailing stuff for Secret Wars
