Stephanie,
I appreciate the concern. Sometimes a mistake is just that, a mistake. The vast majority of those on WikiTree are extremely helpful as you seem to be. The vast majority of people on WikiTree do not know each other personally either (truly in-person). Did you ever have a bit of brain fog when you first wake up? Make a wrong assumption and regret it (your comment) just after you hit the enter key? ...there is no delete key. What I notice happens (sometimes), is that when someone has misspoken, the perception can be that the person is rude or not a team player, when it isn't the case at all. I understand how WikiTree works. Have I been a member a long as others? Obviously not. I have worked on a lot of trees where there has not been a (according to WikiTree standards) valid source, yet they are there and I have either researched and sourced them accordingly. Sometimes I come up with nothing, that happens as well (with me). I find it is important not to be either too impersonal nor too sensitive. What I find important is the recognition that people are valued for putting their hearts into it, but we will make mistakes. Sometimes it's easier to find mistakes in others work easier than our own, and that's because we think in different ways. That's the good thing about collaboration, which sometimes leads to debate. And debate isn't always bad as it often (not always) leads to resolution and improvement. Wikitree isn't perfect, no site is. Neither are any one of us.
