Roger Guffey is a condescending man, railing against the Rev. Franklin Graham and Ken Hamm over their Hurricane Irma comments. Being a prototypical liberal and Trump hater, much offends him. Conservative Christians especially get under his skin.
In my opinion, there are no hobbies or too much free time for a math and Sunday school teacher (what church, I wonder?).
If it offends Comrade Guffey, do what I do with his manifestos: Ignore it.
