That's correct. Dispensationalism is comparable to Mormonism and JW's because they were each invented by one person in the mid 1800's.
John Nelson Darby invented Dispensationalism.
Joseph Smith invented Mormonism.
Charles Taze Russell invented The Jehovah's Witnesses.
Ellen White invented Seventh Day Adventism.
Mary Baker Eddy invented Christian Science.
All of these "inventions" took place in the mid 1800's. That's why this era is called "The Age of the Cults".

You stink, you obsessed psychopath.
TOL pitties those neglected "children" of yours, and that big wife.
Better get to bed, obsessed psychopath, as your Catholic "mass" starts early Sunday morning, little devil boy.
