Two hundred or so years from now, barring some apocalyptic scenario, our transhuman descendants will look back on our time and scratch their heads, confused as to how those curious baselines could be so bigoted towards something as normal as alternate sexual orientations. However, death by old age will be a thing of the past and Earth will be controlled by the ancient conservative elite.
The gap between the rich and poor will widen not just from a wealth standpoint, but a genetic one as well as the rich pay vast sums to have recumbent DNA injected via retroviruses. Their children will benefit from genetic optimization via species modification allowing for the creation of homo superior subspecies.
Various counterculture revolutions will take place beyond Earth in places such as a partially terraformed Mars, the orbital habitats at the L4 and L5 points, near-Earth asteroids, the Main Belt, and the He3 refining facilities on Titan.
On Earth the conservative elite will employ comprehensive memetic engineering programs, forcing the radical to take up more violent methods of argument, which will continue the flow of colonists away from Earth and into the Solar System.
Or, Earth will get fried by a gamma-ray burst, hit by a giant asteroid, or taken over by Islamic population growth. Any of these will result in none of the above ever happening.
