One of my biggest pet peeves has to be the all-knowing genealogist. We've all experienced them at one point or another. The ones that offer "constructive criticism" tinged with an air of superiority. Your research and analysis is wrong but theirs is infallible. THOSE genealogists.
Now, I am all for constructive criticism. Heck, I'm happy if you can prove my research is flawed. I would much rather have an accurate understanding of my family history than to have it full of mistakes and flaws. That being said, there are those who get down right nasty when you present a counter-argument to their "infallible" research. They are more than happy to prove you wrong, but will not see the flaws in their own research. Quite frankly, I have no use for you. Don't even bother contacting me. You will be ignored.
For the most part, I have had nothing but wonderful experiences with the genealogical community. It is a diverse community that ranges from the beginner to the long-time professionals. It is a community of sharing and generosity. It is filled with wonderful people who share the need to know their heritage. So, to all my genealogical friends out there, thank you, for all your help and encouragement. It is noted and appreciated. Whew! I feel better!
