Samesex marriage in the United States   Ive undone your revert on the intro to this article because although its in good faith I think its mistaken The reason you gave was that the information is elsewhere in the article which is already long so the intro shouldnt cover it even in summary as its in the main body under History Although I respect your intent of keeping it concise and avoiding redundancy the Manual of Style for the intro is quite clear  The lead serves as an introduction to the article and a summary of its most important aspects  It should be able to stand alone as a concise overview It should define the topic establish context explain why the topic is notable and summarize the most important points including any prominent controversies  The lead is the first part of the article most people read and many only read the lead  The issue here is that the intro currently says that state bans were declared unlawful in   states provided some rights as from  and Windsor gave federal rights in  There needs to be some mention of the backdrop and prior controversies as they were huge and an increase from  to  paras to add substance on the background  context is in my view appropriate even very long articles still need a proper introduction that summarizes their contents Take a look at AfricanAmerican Civil Rights Movement  for an example of the intro to a longish article   If you disagree with my reasons maybe we can take it to the talk page and raise it theresee what others say first before rereverting    email
