IMO most Stoics wouldn't disagree with the core of your statements, but we would term them differently. Seneca's discourse on anger defines it in a particular way, and no Stoics suggest completely ignoring the "proto-passions" such as the impulse to anger. Stoicism actually emphasizes practices that build the mindfulness to be able to notice that impulse and figure out what to do about it (e.g. make necessary change).
