To Deny or Receive the Holy Ghost
I believe that the opposite of denying the Holy Ghost is receiving the Holy Ghost, that is through baptism. Everyone will have the choice to either receive or deny the Holy Ghost, there is no in between. The only exception to the water baptism requirement is outlined in the scriptures and I believe that those who do not need water baptism (because they don't need to repent) will choose to receive the Holy Ghost through whatever other means God has provided.
This is a little confusing, possibly, because Jesus needed baptism to be saved but did not need to repent. However, the only exceptions are to those not accountable. Christ was accountable. The only reason that there are exceptions is because the merits and mercies of Christ save all those who are not accountable for sins, their own or that of others.
