Centerists, or people who voted for Biden in the primaries tell progressives and leftists we’re minority viewpoints within the Democrat party. Implying that we have no business trying to influence the direction of the party. These same centerists also blame us when their garbage candidates don’t win in the general election and tell us things like “Biden was a good compromise” or “You got pretty much everything you wanted” despite neither of those things being true.
Centerists got so comfortable winning elections on their own they forgot how to compromise and accuse anyone else trying to negotiate as “throwing a tantrum”.
