That is just the nature of the beast when making a claim of producing something new. I've had to run that gauntlet several times. The questions and doubt can vary anywhere from truly thoughtful and introspective, to being obviously outlandlishly petty and ridiculous. But that's just the way real life is.
And yes, people do have a right to question someone else's hypotheses and data. Very few people are willing to accept claims at face value, no matter who the source. Personally I believe peer review of anything of this nature is immensely important and should not be blown off simply because it may hurt someone's feelings to not be taken at face value. It's rarely a personal issue, but instead people are trying to be certain that the hypothesis and assumptions being presented are indeed valid.
Data indicating the likely source of the bloodline is important. It can help identify the relationships with other genetic types as well as provide a source tree showing not only where the line came from, but also likely avenues of transmission to determine where this new unique gene might likely surface. Such answers will help immensely when someone else produces the same genetic type and instead of claiming it is something new and unrelated, can logically deduce that because of the likely source, comparing notes from existing examinations of similar looking animals can save a LOT of time and trouble trying to figure out exactly what it is they now have on their hands.
Just because this may be a hobby and merely a fun pastime to you doesn't mean it has to be for everyone else as well. Some people will need to make decisions based on this sort of data that could have them wasting lots of time, money, effort, and resources on projects if the assumptions made are not what they appeared to be at first blush. They could be making plans that could cost them thousands of dollars over several years. So please don't blame them if this is much more serious to them then it may be to you.
