What's deeply ingrained? Like I said, HUNGER is as deeply engrained as any human desire we could possibly have, but even hunger has virtually no influence in the important decisions we make, such as what career to pursue. Hunger is obsolete. We feel hunger as a biological necessity, one that forced us into action on a daily basis in primitive times, but it's moot now. You could literally sever the connection between your brain and your stomach so you'd never feel hungry again and, as long as you kept feeding yourself (which you would do, since you already know it's essential to your survival), you'd be totally fine.
People don't have to "shun" their gender identity or whatever inclinations are associated with that. Whatever inclinations people have, you'll see great enough variation among members of the same gender that whatever general variation exists between the genders is inconsequential.
