No, absolutely not.
Believe it or not, some adcoms for DO schools actually wanted your genuine reason as to why you'd want to attend DO school instead of just throwing the same generic reason( Oh, because DO is holistic). (I got this vibe a lot from just going to the interviews)
It is true that DO schools compared to MD are sometimes at disadvantages when providing students chances of getting into top specialties like something in surgery.
But they give you that chance of becoming a physician nonetheless and you still have a shot at being a surgeon.
