Yes, he’s specifically condemning Evangelicals because they are the kind of Christians who take seriously the message of the Bible and refuse to water it down with religious pluralism. Many conservative Catholics, Greek Orthodox Christians, and more traditional Protestants would also fall into this camp.

‘Liberal Christianity” or ‘Ecumenical Christianity,’ on the other hand, is not really a threat to liberals because they don’t espouse ‘hard’ Bible doctrines such as eternal punishment, condemnation of homosexuality, sin, God’s wrath and Christ as the only way to God. They are essentially liberals, except they wrap themselves in the banner of Christianity or religiousity. They employ the language of Christianity, but give its major doctrines foreign meanings never intended by the writers of the New Testament. Secular liberals understand this, and that’s why they don’t feel threatened by ‘gay’ churches or ‘ecumenical’ churches that teach there are many ways to God.
