This thread started because someone was asking for genocide in the sense of death camps/direct massacres during peacetime to eliminate undesired pops as a mechanic, and specifically said deportations were not enough for them. Most people have taken that meaning, plus the dictionary defines "genocide" as the "(1) deliberate killing of a large number of people from a particular nation or ethnic group with (2) the aim of destroying that nation or group." (Oxford Dictionary). As such, although some people expand the definition, most of us in the thread have been referencing this narrower definition, which does not technically include deportation or most pillaging in this period.
Sorry if a lot of us have been talking past you. There is much more support for deportations and pillaging in game, since that happened frequently during this period. On the other hand, most of us oppose a "government exterminates pops" button because it would be historically inaccurate and unrealistic as a mechanic. The Taino situation is being handled by the pestilence and slavery mechanics.
There are only a handful of events from this period, like the Dzungar, that do not fall under deportation and pillaging which are already modeled. It would mess up the game if ahistorical extermination programs were introduced. I would also point out that you don't see people on the forums calling for slavery not to be modeled, even though that practice was terrible and remains a big political issue.
