Ah yes, the old discussion poisoning fallacy of "drawing a straw man and implying the other party are hypocrites for not following/implementing/adhering to the straw man".

And somewhat less abstract: if someone argues in favor of a smaller government, they are not automatically anarchists that think there shouldn't be a government at all. Painting a world without a military and challenging them to go live in that world is not a proper counterargument.
