I wonder if this is even a genuine, if misguided, Christian preacher. Could it be a false flag?
Kevin Swanson is an ordained pastor in the Orthodox Presbyterian Church. You can hear his radio show on the Sermon Audio website. I can assure you that Kevin Swanson is well-known in home school circles and in the family-integrated worship movement. He frequently shared a stage with Doug Phillips of Vision Forum before Doug Phillips' resignation.
Even when I agree with Kevin Swanson, his over-the-top dogmatic style is hard to take. I haven't seen Frozen but it wouldn't surprise me if Kevin Swanson's criticism is misguided.
