Religion in general is as much a matter of faith as it is of knowledge. Expecting anyone to defend, or prove, their faith logically should be out of scope for this site, as there's really no objective way to prove "faith", any more than there's an objective way to prove that God even exists in the first place. That is not what this site is for, nor should it ever be.
We are a site for sharing knowledge, not for proving which interpretation of that knowledge is "right" or "wrong". It's fair to assume that all Muslims believe that what they believe is right, and that nobody likes being told to defend themselves.

Treat others with the same respect you’d want them to treat you because we’re all here to learn, together. Be tolerant of others who may not know everything you know, and bring your sense of humor.
Unless the question can be worked to point to a particular evidence (e.g. Why does such-and-such school reject this hadith?), I feel that such questions should be treated as off-topic for this site. Any question which starts with the premise that anyone who is expected to answer it is wrong by default is unlikely to ever be constructive, if only because it's outright rude to the people who volunteer the time to actually answer the question.
