The response ' the questions aren't simple and neither are the answers.'
Seems to be a standard TRA response for failing to be able to answer the most basic questions about their core concepts or for failing to define the absolute most key terms in their position.
They seem to have redefined this as a virtue, as if it shows how clever and complicated their position is, far too clever for those simpletons who expect basic coherence in foundational concepts.
How can they honestly not see how this is a self-serving and frankly stupid line of argument to take?
If you can't defend your key position, its probably because its not defensible.
