Hello Cielomobile. I have to say that I also belive that the edits made recently to the United States-Mexico barrier page were not vandalism. I understand that the topic of the border can be polemic, but I don't think that User:68.2.242.165 was vandalizing the page. Maybe you could use the talk page Talk:United States–Mexico barrier to lay out your objections to those edits without deleting them entirely. I think they were good-faith efforts to improve the article, and that is also one of the guiding principles of Wikipedia, to Assume Good Faith. It might help though, if the author of those edits were to register with Wikipedia so the edits won't appear merely with an IP address.
