I agree with most of this, I just don't think we can afford to discount the power of stigma when it's easier to go around that stigma and choose other names to unite under. The left has no problem getting hateful and even simply distasteful words out of common usage by drawing attention to what makes them problematic, sometimes even with proposed changes that are more inflammatory than the original (Looking at you, "Latinx"). I don't see why we can't do the same for the term "Socialism" and use something with less historical baggage in order to better appeal to moderates without sacrificing any actual ideological shifts.
