In my view, there are three cliques. Contra Points' crowd, debate bros, and leftover channels that do not quite fit into either category. This might not be the perfect way to categorize them, but it is simple and straight forward.
Contra Points' crowd: This includes people closely affiliated with and ones idealizing Contra Points. Contra Points is at the top of the group. People like Philosophy tube, Lindsay Ellis, HBomberguy, Dan Olson, and others who were in vidcon photos are one step below. Bottom of this hierarchy is made of small channels imitating ones above them, hoping to become one of the other big names. People in this crowd release video essays, many like to use skits, and have tendency to copy contrapoints' aesthetic. They are the most politically correct, focused almost solely on social issues, obsessed with social media, and most likely to defend corporations because of publicity stunts pandering to progressives. High production values. Most likely to get in trouble due to not being PC enough or by hanging out with non-PC people.
Debate Bros: Men debating and owning alt-right, reactionaries, or whatever the flavor of the month term is now. Destiny and Vaush are the biggest names here. Then there are people who ideolize big name debate bros, and their proteges like Xanderthal. They are the least politically correct. Their focus is on owning people, pointing out "bad takes," and complain about capitalism as they profit off of patreon and superchats. Low production values. Most likely to get in trouble due to making stupid decisions.
Others: Anyone else who does not fit into above two groups, some implying that they are not part of the breadtube despite sharing an audience, politics, rhetoric, and many other elements. These people tend to rant at the camera about politics and little else, and tend to put more effort into hiding their real identities than other two groups. They are mostly smaller, niche channels like Three Arrows, Beau of the Fifth Column, and Hakim. This groups has the most overt commies out of the three, makes the least money, gets the least attention, and cares about being PC slightly more than Debate Bros. Production values tend to be inbetween the other two groups. Tend to fizzle out before they get in trouble.
It's not a perfect breakdown, but should be enough to give you an idea how the landscape looks like.
It's not that weird. Communism has a LOT of different flavors. You can be anything from Stalinist to Anarchocommunitst and even combine different ideologies. Infinite amount of options appeals to the same people obsessed with obscure sexual identities and using custom pronouns. That's what happens when stereotypical tumblrites get interested in politics.
