Ranked choice means it’s easier for voters, but when it’s not available voters are capable of understanding the scenario you describe and voting accordingly.
Many times I haven’t voted for my preferred candidate and instead voted for the candidate most likely to defeat the candidate I couldn’t stomach getting into power. Here in Canada we call it voting strategically and if you look at the polling data it definitely happened last election (and in many others in the past).
I’d like to have ranked choice, but it’s insane to say it’s not a democracy without it. But multiple rounds of voting (like France has) is better than ranked choice as it gives a clear choice to voters in the final round. But having multiple voting rounds is expensive and people might prefer to just vote once and have it done with, so ranked choice may be preferable for many people.
So you think that some speech should be banned?
