Actually, it's this move of yours that looks unfair. "Ideology!" is not a claim that can be leveled at any positive claim. If a claim is based on logic then you can follow the logical chain and, if it's sound then it's sound. But this claim of yours was not such a claim. It was a premise for further claims. I provided reasons for thinking that at best it is unverifiable and at worst it is just wrong. If you don't like the word "ideology", we can call it an "unexamined assumption", an "expression of preference" or a "statement of worldview". But it most certainly is not unfair to point out that it is not a product of logical thinking.
