Q. I am writing a paper for ID301 and assigned a web debate for use. I have not been able to find a source to show how to reference and cite a web debate in MLA style. Can you help me?

For newspaper editorials (which your source exemplifies because it contains several different viewpoints), you would need to cite it as a newspaper editorial article. See the first link below (or go to https://owl.english.purdue.edu/owl/resource/747/07/). Scroll down to "An Editorial Section.." Also, review the basic MLA format for electronic sources. See second link below (or go to  https://owl.english.purdue.edu/owl/resource/747/08/)  Scroll down to the section on Basic Styles for Citation.
You will be citing the source as an electronic newspaper editorial.
