I found this rather obscure figure several months back through Assigned Male's Facebook page. John Harrison is a part-time preacher and guitar player for the small Fairfield Heights Presbyterian Church in Birmingham, Alabama. When he's not at church, he's devoting his time to drawing his heavy-handed and sub-par political cartoons to post on his social media, where he proudly labels himself as an SJW.
His favorite topics for lampooning include the governor of Alabama, Robert Bentley, whom Harrison has unaffectionately "Cadaver Bob" because he's old and skinny—I guess—and, more recently, President-elect Donald J. Trump.
Harrison's largest project is his web-comic/soap-box Guitar Girl, in which a large-breasted teenage girl named Katie espouses all of Harrison's left-wing ideas. Besides being the young, left-wing activist that Harrison wishes so hard that he was, Katie's only character is that she likes playing the guitar and wants to buy a Fender Telecaster, an aspect of her character that guides what little "plot" there is in the comic on the rare occasion that Harrison has nothing he wants to say about politics. Other characters include Harrison's self-insert, who is Katie's father in the comic; Katie's gay Black friend, who shills Black Lives Matter three comics in; and Katie's vaguely brown friend, who dreams of working for Al-Jazeera.
Notable pages include one where Harrison couldn't think of a situation to create to talk about Syrian refugees, and thus simply had Katie lecture the reader directly, and another where Harrison couldn't even be bothered to add color.
Despite being a project Harrison has been working on for over a year now, the entire comic can be read through in about 15 minutes. The most recent comic involves some new fairy character doing her best Carl the Cuck impression.
Trump's recent victory has also caused a great deal of mature political dialogue on Harrison's Twitter account. One can expect this trend to continue.
Harrison is also a big admirer of both Sophie Labelle and the Trans Lifeline:
