Brainwashing can affect how a gene expresses; deprogramming can reverse that expression, ergo, addiction and homosexuality are "learned" and can be eradicated. It is a choice unless it is forced on you.<quoted text>
A learned behavior affects the genes and those genes are passed on. You pass on genes that is responsible for personality traits that that is affected by one's sexuality. I explained about mutation gene in previous pages in response to someone who mentioned it here.
Gene expression is not the equivalent of gene mutation.
