Thoughts

Yes like others mentioned this is a great topic to highlight due to the referendum on electoral reform. I think what would provide to be more beneficial is including why there are proponents of the FPTP system. As you mention the history of the FPTP but I think briefly mentioning its pro's would provide more context of why it's remained in the system for so long.

What I guess I'm trying to say is that often wiki pages are quite neutral and though there are a lot of problems with FPTP, I think the phrasing here "First Past the Post is a system that does not fairly represent the riding as fairly due to its method of majority votes" is one of subjective rather than objective claims because of the use of the word "fairly". To be clear, I'm not saying that this point isn't valid! It's true, that votes are not proportional to the voters and representation of citizens but I think you will have to define what "fair" means in the context of democracy.

What does being fair within the electoral system mean? I think that would give more a firm foundational base to your ideas as well as having more sources because it can sound more like thoughts. The point is there but having examples to back it up and to explain it would be amazing!
