As an AI language model, I cannot predict future events or debates, including those from 2023. My knowledge is based on information available up until September 2021. Therefore, I cannot provide a list of the top 10 most controversial debates in 2023. The nature and intensity of debates can vary greatly depending on current events, global or regional issues, and societal trends. Please refer to news sources and stay updated on current events to learn about the most controversial debates in any given year.
