[Okay more like 拉丁美奸 but you get the point]
Gusanos are mainly just emigres who leave because they lose their property/slaves or hopes of gaining property. These “Venezualans” aren’t just that. They support the murder of their countrymen. They are collaborators of genocidal imperialists, and Venezualan in name only. Gusanos are thieves and slanderers, 汉奸 are nothing less than prions
Colourism and anti-black/anti-indigenous racism helps with the reaction; in fact the material conditions enforcing these maybe the primary component here.
