You are looking at reddit solely through the lens of politics. I do agree that it is not a great place for political debate. However, would you allow for the fact that setting aside USA national politics, there is a lot of value? I subscribe to subreddits about kombucha making, MTG, retirement saving, minimalism, and in those areas there is quite a lot of reasonable discussion.
That's my primary use case for reddit. I joined more than 10 years ago during the big digg migration. I think there are many wonderful communities in the space and it is something to cherish. But when r/news is a default subreddit and the majority have power to sink opposing viewpoints I think it merits a discussion on the importance of diversity of thought.
