He didn't ask you to extol the supposed virtues of Jainism. He asked if you were a Jain. That's a pretty straightforward question that can be answered yes or no. Why are you avoiding it?
Most individual religions are unique. Sure, they may fall into broad categories, but you will always be able to find something about each individual sect that makes it unique. Jainism is not unique in claiming to be unique.
Jainism is not natural in the sense that it follows from nature. Jainism imagines a model of nature, the same way Mr Tokien imagined a world that resembled pre-industrial Europe and included magic. The Jain model doesn't model actual nature. Just because you can imagine it, and because it corresponds superficially with what you can observe, doesn't make it true and correct in all respects.
Jainism is surely ascetic, but don't confuse a draconian lifestyle with moral rectitude. As we have pointed out, Jainism certainly hasn't taught you how to be a moral person such as in how to respect others, so I question its claim on that basis.
The claim that Jainism is scientific has been examined and rejected. We found that Jain scholars are simply willing to lie about what science is and what scientists have concluded. I surmise none of the intended audience for that writing knows much about science or is motivated to learn, hence it's a lie that can be told with relative impunity. We have seen all manner of dishonesty and evasion from Jains as they squirm under the examination of actual scientists. There is obviously a strong desire for Jains to portray themselves as scientifically justified, but the facts simply don't show that.
But the question remains: Kumar, are you a Jain?
