Not that part, just to equate defending the scouts right to practice morality in excluding sexual deviants to defending Larry Flynt's right to print his material.
The left doesn't like the Scouts. The left doesn't like Flynt.
Neither sees the point: When the will of the majority is used to violate the rights of others in pursuit of morality, you empower your opponent to limit your own rights.
The left sees discrimination as immoral. The right sees pornography as immoral. Both hand the government a big stick. Soon enough, government is staring at you. And he's holding the stick you gave him.
