Yours isn't an uncommon feeling. I've felt that way too on occasion. It's one thing to be there, in person, working with others; it's another to be collaborating online, with people acting separately.
I'm guessing that your current issue is primarily with the actions of one overzealous "Data Doctor" on the profile of Moses Duke. Is that correct? From that it seems that you have a fair contention.
The following is mixed with a generous amount of opinion, as I can't be certain of why that merge was undertaken. But, such erroneous actions are frequently a problem with people acting as WikiTree's "Data Doctors": they have become accustomed to undertaking edits in accordance with the mere suggestion from an algorithm operating on the database, rather than editing solely when justified on the basis of further documentary evidence.
Despite their good intentions (as good intentions when acted upon often have unintended consequences), people still make mistakes and (unintentionally) break rules. Violations that I have personally observed among Data Doctors, contrary to their mandate, include the removal of information from a profile and failing to "contact the profile manager through a private message before making any changes".
It gets further complicated when WikiTree rewards users based on the number of their edits ("Club 100" or "Club 1000", anyone?), rather than in keeping with their contributions' quality, thereby incentivizing a different focus: apparent quick-and-easy edits. So that further complicates the situation.
But I would encourage you to persist. Although tedious, a bad merge can be fixed! Moreover, you can prevent further dubious edits by flagging another profile as a "Rejected Match". Remember, WikiTree is a "big tent" in terms of skill levels and backgrounds. It sounds like you've had some time to hone your skills, but remember that many others are still in that process. Despite our variable skills, we all share common ground in the desire for this to be an evidence-supported enterprise, in which we seek to be excellent to each other, as expressed in the Honor Code. But everyone will make mistakes occasionally and many of us are learning as we go, so a polite little nudge sometimes helps.
