Your assertion that trait carries suffer genetically from SCD is patently absurd, they don't have, and will never have SCD, so how could they suffer from SCD traits. All human tissue is subject to certain environmental factors, related to their particular human genome.
Sickling is not a problem with trait carriers. Sickle cell disease.
Not hardly...I'm referring to the complications suffered by those with SC Trait-aside from those with SC Disease-as defined by the genetic definition...your assertion that trait carriers cannot be sickly-do not suffer complications-is patently absurd...
