She kinda has a point - in a way, as harsh as it may sound, that is a good way to describe it...
I find it interesting to see someone I think of as being more 'conservative' using a more 'liberal' tactic like using 'anti-dispensationalist' to describe someone.
I am thinking that [at least] the absolute majority of those who do not agree with dispensationalism do not "hate" it so much as they love the truth and want to abide in it, share it with others, and rebuke/reprove false teaching of the scriptures.
Dispensationalism has subtly changed the nature of God and the nature of man. They say that man is under ”conscience, law, grace” or whatsoever in different “dispensations”, while my Bible says that God was, is and always will be, and man is always sinful, fallen short of grace and in need of salvation. The way I see it, this heresy is a marketing strategy, it dices and slices the Bible into different portions, and anybody can pick their favorite which they think suits them. They don’t need to read the whole Bible and see the bigger picture, they just need their own “dispensation”.
