r/LateStageCapitalism is on the front page all the time. Its rules include "Support for capitalism--and the political parties which uphold it--is strictly prohibited". Counterbalanced views are not front paged on a regular basis.

Reddit made sure idiotic pro-Trump subreddits were left off the front page. It didn't do the same for idiotic anti-Trump subreddits.

r/TwoXChromosomes, also regularly appearing on the front page, is about as liberal and pro-choice as you can get.

I don't like Trump at all. All the things going down right now were easy to see coming. But he got well over 40% of the popular vote in the election and still has millions and millions of supporters. Absence of pro-Trump viewpoints on the reddit front page is conspicuous, in my opinion. Likewise any number of other relatively popular viewpoints.
