Of course, I don't agree with his views, particularly placing The Origin Of Species directly next to Satan, which isn't just coincidence, since he claims to have had a reason to place every person in each position in stances for set reasons.
I don't know how your politics truly work in America, and it seems much more complicated with the number of different positions that people can have in politics, (Of course that's expected with as large a country as America), but it's clear when people are smearing as much biased criticism as they claim to despise, which this painter clearly does.
It's a real shame that politics and religion finds its way into every form of Art these days.
I'm sure I'm not the only one, but some people like to just enjoy Art without having to listen to it's one-sided messages.
