You are challenging their religion (as dispensationalism is a type of cult), and the object of their worship. Making beef of their sacred cow, so to speak.
I am thinking they are somewhat realizing they have bought into a lie, since that little nation is acting anything but God fearing, and they are doubling/tripling down.
When truth is deep inside of you by the Holy Spirit and you are acting within God's will by proclaiming truth there is liberation,
Dipseys do not have liberation, they have entanglement they are trying to defend and it makes them angry, much like Calvinists.
Do they realize how many people will need to die for that land to be regained.
It is pure insanity.
