How Should You Answer المذهب (Sect) Question on Your Umra Application?

An acquaintance shared with me his umra visa application. On it, I noticed that the pilgrimage authorities ask for المذهب, which is translated as sect.

umra-visa - cropped
I wonder how the authorities would act if an applicant wrote:

ما ألفيت عليه آبائي

What I found my forefathers practicing

I’m so sick of sectarianism.
