And I don't get where he gets this idea from, because the Bible is saturated with passages that condemn LGBT people. "Detestable," "abomination," "perversion," "they shall not inherit the Kingdom." That is what the Bible has to say about LGBT people. And not only that, it says to kill them.
And Jehovah doesn't disown his children? "I never knew you, depart from me" is what Jesus has already said he's going to be saying to many of those who follow him (Matthew 7:23). He also warned against lessening and changing the laws and said those who do will be counted among the least in the Kingdom.
