Editing the lead
SSZvH7N5n8, could I ask you again to discuss any substantive changes to the lead here on talk first? The current lead has consensus, both from this most recent discussion, and from a previous one (thinking now in particular about the second paragraph), where Bilby, who has an academic background in this area, was very helpful in suggesting how to approach it, and agreed with the end result. 

The changes you made to it  removed the two key names, and left it reading oddly. This is the lead section of the parent article of the animal rights pages on Wikipedia, so the writing has to be reasonably clear. That doesn't mean it's written in stone, but please suggest changes here so that we can consider your arguments.

Also, "animal rights" and "animal liberation" are used interchangeably on Wikipedia and throughout most of the academic literature.  (talk)
