Who are “they”? What other systems are they advocating for? All I ever see on Lemmy is people hating FPTP (rightfully so) and in favor of RCV (rightfully so) with the occasional person remarking on limitations or (more commonly in my experience) saying it’s not a magic bullet solution and is only part of comprehensive reform. An kmportant part of it, no doubt, but still a part and a lot of people seem to overestimate RCV‘s ability to save us.
