"The theory suggests that emotions are vectors through which the genetic condition necessary to develop stuttering manifests." That is not a claim you can provide evidence for, it's exactly the same as the claim you made earlier. If you can provide evidence for it I'd love to read it. Nobody is saying that emotions don't influence stuttering. However, as you seem to agree now, they aren't as significant as you once claimed in the pathophysiology of stuttering. "there are studies regarding the relationship between stuttering and dopamine (also quite theoretical), there's a lot out there, and little evidence hahaha" This statement contradicts itself. How can there be a lot of studies out there on the relationship between stuttering and dopamine yet simultaneously, you claim, there's little evidence? Anyway, it's important that we use evidence to back up our claims. There's no point going round and round in circles on personal theories when the answers you're looking for are in the research you're avoiding.
