A devil's advocate would say that most professional crew have not experienced a real technical failure leading to a high-speed RTO.
CRM is a red herring if everyone is briefed and knows what they are doing in the flightdeck - either approach can be feasible and right.
What is not acceptable are jumpy FOs calling RTO for minor occurrences, and Captains who don't listen to the best advice of their highly-trained colleagues albeit with less flying time.
Black and white is never right...
