Because we're seekers of truth, not partisan sophists?
Edit to clarify: I want to know the truth, so the burden of proof is always on me. If someone doesn't have the time or energy to make a full argument, I still appreciate their input. I will try to learn from it if I can. I don't want to silence people who can't write a book on a given topic.
I never asked for a book. This guy is making rhetorical questions equating donation to bribe. Sounds sophist to me and definitely deserving a challenge.
Apologies, I thought it was established that some donations are highly likely bribes [0]. If you're questioning that basis I certainly don't have the interest to debate that with you. Assuming you agree on this premise, then I certainly am equating these types of donations to bribes.
