There must have been enough up votes to counter the down vote you saw, because I'm seeing +1 right now.
I can only guess, but there are a lot of members on WikiTree and everyone is welcome here. I suppose it's possible that we have a few members who don't share the WikiTree spirit that I have found so overwhelmingly accepting and supportive here. Perhaps that Iranian nutcase who claims the Holocaust never happened is a member ... or maybe a member of one of the several terrorist organizations that still think Jews have no place in this world.
Anyhow, I wouldn't be bothered by it ... I realize that there is a lot of hatred directed at all sorts of things ... it's not my thing, nor is it at all representative of EVERYONE - without exception - who I have encountered here.
This isn't even my family ... I started by volunteering to help whittle down the list of unsourced profiles and picked the first one on the US list - his last name began with A. It turned out that he had a wife, parents, siblings, and children who were all unsourced but not on the list, so I decided to deal with them all. From there it snowballed and I discovered that there are about 500 of them all from the same gedcom and they are all completely devoid of anything meaningful, either in profiles or sources and there is no profile manager, so I "adopted" them all ... and that's where I got to this point!
