Perhaps it depends on the definition of “views”

During a discussion at Southern Methodist University, Supreme Court Justice Antonin Scalia maintained that “I haven’t expressed my views” on gay marriage or gun control.

But, as The Huffington Post points out:

In his dissent in a 1996 Supreme Court decision overturning a voter-approved, anti-gay referendum in Colorado, Scalia wrote in support of the voter majority, "I had thought that one could consider certain conduct reprehensible -- murder, for example, or polygamy or cruelty to animals -- and could exhibit even 'animus' toward such conduct."

And in 2003, after the Supreme Court negated a law in Texas that had criminalized same-sex "sodomy," Scalia wrote in dissent, "The Texas statute undeniably seeks to further the belief of its citizens that certain forms of sexual behavior are 'immoral and unacceptable' -- the same interest furthered by criminal laws against fornication, bigamy, adultery, adult incest, bestiality and obscenity."

So, is Antonin Scalia against gay marriage? You might well think that.  He couldn’t possibly comment.
