RCV doesn’t “solve” the issue though. The fact that third party candidates can sway elections to the least preferred candidate is known as the “Spoiler effect”, and RCV is also subject to it.
RCV seems to be objectively better than plurality (what we use now), but it and any other ranking-based voting system are still subject to spoilers. One thing that can actually “solve” the issue though is rating-based systems, like Approval Voting, Score Voting, or STAR voting.
Is there any particular reason you’re being so inflammatory? OP comes off as asking genuine questions in the interest of developing a better understanding and sharing it with readers. To back what they’re saying, ‘at the minimum it’s disparaging and could discourage others from asking questions.’
