Riley , l felt quite depressed by your comments about Evangelical Christians.
Are you American? , the use of the word Evangelical makes me think so .
I don't know if he is American, but I would guess he was using 'Evangelical' from an American or at least North American point of view.
In America it is kind of a catch all term for a certain type of poorly educated, extremely conservative religious busybody, intent on foisting their narrow worldview on the rest of the country. But, because they are good at getting their church members to vote in large numbers, politicians (mostly Republican) pander to their nonsense whether they personally find them repulsive or not. Because they bring votes.
