Here are some other quotes from Scalia's opinion which are obviously very homophobic...
State laws against bigamy, same-sex marriage, adult incest, prostitution, masturbation, adultery, fornication, bestiality, and obscenity are likewise sustainable only in light of Bowers' validation of laws based on moral choices. Every single one of these laws is called into question by today's decision.
States continue to prosecute all sorts of crimes by adults "in matters pertaining to sex": prostitution, adult incest, adultery, obscenity, and child pornography.
The Texas statute undeniably seeks to further the belief of its citizens that certain forms of sexual behavior are "immoral and unacceptable," Bowers, supra, at 196--the same interest furthered by criminal laws against fornication, bigamy, adultery, adult incest, bestiality, and obscenity. Bowers held that this was a legitimate state interest
As you can see in these passages Scalia repeatedly compares gay sex to bestiality, incest, prostitution and child porn. That is homophobic, and that is not all he says.
Today's opinion is the product of a Court, which is the product of a law-profession culture, that has largely signed on to the so-called homosexual agenda, by which I mean the agenda promoted by some homosexual activists directed at eliminating the moral opprobrium that has traditionally attached to homosexual conduct.
Yes, the "homosexual agenda" a phrase that tends to be uttered primarily homophobes who say things like what Scalia goes on to write about...
Many Americans do not want persons who openly engage in homosexual conduct as partners in their business, as scoutmasters for their children, as teachers in their children's schools, or as boarders in their home.
But after he says all of that crap comparing gay sex to bestiality, child porn, and prostitution and suggesting that we need to protect our children from the "homosexual agenda" by not allowing gays to work in our businesses or be scoutmasters or teachers, he says the words you quoted. I find it interesting that you leave out all of his preceding words and pretend like all he said was "I have nothing against homosexuals" when it was very clear by everything he wrote beforehand that he is a homophobe.
