There is a very specific claim I want to run through skeptics. This claim is very common within an internet subculture. I would like to get a through and definitive answer to it, but I'm having trouble providing notability despite it being very notable.
My problem is that the subculture lacks a single person of sufficient importance for me to site, and I don't have a good way to prove that the claim is very common amongst every day individuals in the community. However, I think it's not only notable form my experience but quite important.
In this case I'm wondering how best I could build the question.
To give specifics for my case I want to ask a question about a rather unique group, known sperm donors. These are men who meet women and donate sperm to them in person, without going through a bank. They are a small group, but there is a very very common claim within that group.
Specifically when looking at these sperm donors about 1/3 to 1/4 of all donors will claim, directly or indirectly, that NI (natural insemination, basically sex) is more effective then AI (artificial insemination, done with fresh sperm at home). I have my own beliefs on what seems most likely here from my own research, but I want to get a third party site like this one to investigate it and give a good answer that can be referenced whenever this debate comes up, the closest thing to a definitive source.
Considering the frequency of the claim and degree of contention it can cause I consider it to be very notable, for anyone familiar with the known donor community, which is likely no one else on the site, it would be common enough to not even require a quote per site rules, but I can't prove that. I can provide dozens upon dozens of quotes of men making this claim, but since none of the individuals is well known no single quote I provide counts as notable. The community itself is so small that it doesn't really have anything like a celebrity of sufficient notability to be quoted at all.
Well, that isn't entirely true. One of the closest things to a 'celebrity' within the community is, unfortunately, a sperm donor who goes by the name JoeDonor (aka fatherofFour) who has made this claim many times. This individual has been on 20/20 twice and in a number of news weeks articles, and has even self-published 'books' which I know make the claim (https://www.amazon.com/Joe-Donor/e/B00J59W7BW). However, I don't have an exact quote from any of these books, because I refuse to pay even a cent for any of those supposed books, the individual writing them has been guilty of some pretty horrible things and I refuse to give him any support, financially or otherwise, if I can avoid it.
I can provide plenty of quotes outside of the book by this donor, but since no one but me knows who he is I don't know how to provide proof that he would count as 'notable' within the community.
Thus my question, what is the appropriate manner with which to go about proving notability to sufficient level for the question to qualify for this site?
