I think you are right and debate is needed, but unfortunately on online platforms debate is really hard to keep civil and respectful. On platforms like HN where the audience is somewhat selective and moderation is possible you can have a reasonable debate, however on platforms like YouTube where views are money it can be difficult for creators to not play to the algorithm and go for the click-bate title with the emotive thumbnail with content that will attract the most views. I think YouTube, by removing the money making imperative is at least removing that driver from the equation whilst leaving the possibility of still posting controversial material and allowing debate.
