Sounds to me like he quoted or paraphrased I Corinthians 6:9-10. It wasn’t just his personal opinion. If that’s the case, GLAAD’s beef isn’t with him, it’s with the Bible:
1 Corinthians 6:8-10
New International Version (NIV)
8 Instead, you yourselves cheat and do wrong, and you do this to your brothers and sisters. 9 Or do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men[a] 10 nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God.
Footnotes:
a.1 Corinthians 6:9 The words men who have sex with men translate two Greek words that refer to the passive and active participants in homosexual acts.
Someone needs to tell GLAAD that.
