Having pointed out that Jerry Falwell, Jr. is one example of a current phenomenon known as #FakeChristians, Mrs. Betty Bowers, America's Best Christian, thought it wise to generalize her advice to more widely identify the species as a whole, as a public service to those not so well versed in identifying such. This she does with great economy, needing hardly more than a minute and a half to accomplish.
I therefore leave you in her expert hands:
Have You Had YOUR Betty Today?
Good thing we have her to educate us.
