Brian Brown, president of the National Organization for Marriage (NOM), remembered Supreme Court Justice Antonin Scalia, who died Saturday of a heart attack.

The leader of the nation's largest group working to undermine the court's June finding that gay and lesbian couples have a constitutional right to marry called Scalia a “giant of a man in every way.”

“He was a faithful Catholic, loving husband and devoted father,” Brown wrote. “As a lawyer and judge, his towering intellect helped shape the law and counter the unceasing pressure by liberal jurists to move the country to the left based on their concept of an 'evolving' constitution.”

Brown praised Scalia's dissents in cases involving gay rights, including Lawrence v. Texas, the 2003 case that struck down sodomy laws in 14 states.

In Lawrence “Scalia skewered [Justice Anthony] Kennedy and the majority for basing their decision not on the constitution but on the observation that the Bowers ruling had been repeatedly publicly criticized,” Brown wrote. “Justice Scalia presciently warned that the ruling would inevitably lead to gay marriage and the striking down of laws against polygamy, bigamy, adult incest and bestiality because the Court was effectively banning states from considering the morality of sexual practices as an intrusion into the personal and private life of the individual.”

“That is why we absolutely must elect a proven conservative champion as president who we can trust without question to appoint a constitutionalist like the late Justice Scalia,” Brown added, referring to Texas Senator Ted Cruz, a vocal opponent of LGBT rights.
