I just recall that De728631 has been considered involved after he blocked me during 3 days, a decision proven unfounded and cancelled after the appeal from  . It is cristal clear that there's nothing solved here, and I agree with ,  and  that the article has many other flaws that we could address first. 
 Culture: the section is indeed too big and should be thought as a glance inviting the interested reader to explore the Culture of Paris detailed article. We can also feel a certain trend to mix that section up with the more mainstream Culture of France article. I think an overhaul is necessary in order to focus more on the key elements to understand what is specific to the Paris identity: theatres, the movie industry, impressionist school, few key writers and singers, and the current state of today's Paris cultural life.
 Landmarks by district: that section, currently listing 450 different buildings, is totally unreadable in its current form. It should be replaced by a more general "Monuments and Landmarks" section, if not by an even broader "Visitor attractions" section with not more than 20 different mentions. Once again, there is already a standalone article for the Landmarks in the City of Paris which is more reader-friendly for those wanting to explore a more detailed list of those.
Even if that doesn't solve ongoing conflicts, focusing first on these 2 sections is probably the best way to get back to more constructive contributions to the article.
