== Neutrality? == 

 This sounds to me more like an essay supporting the amendment than a neutral presentation of the topic. Though you have a commendable number of references in explaining support for the amendment, the opposition section seems to rely on unnamed opponents ("some claim", "some hold", etc.) which isn't a great practice. Also, every paragraph in the opposition section seems to end with a response from proponents, while the section of arguments in favor doesn't have that practice. 

 Statements like "this argument confuses" or "these sources do not provide explanation" are the opinion of the author and aren't presented neutrally. Instead, attribute those arguments to a particular source. Otherwise, the article is non-neutral and represents original research. 

 Hope this helps,
