LOL. What a friendly note you made. 

Go ask the admin . He agrees you should NOT assume contributors are "acting in good faith, and assume good faith on the part of others". You contributed. He considered you are a vandal because you mentioned a bad source in your contributions. Leave remarks like "Its a vandalism and pov-pushing magnet". Threaten you to ban you if you further edit this page. I just learn from him.

Funny. Removing all contributions because there are some mistakes in that article is the norm here!

After all, when someone can simply discard all contributions made by hard-working contributors as a way to welcome new contributors, what kind of respect would you expect?
