Zerosumming
Making things into a zero sum game, when they don't have to be. That harming one group inherently benefits another group, and vice versa. Zerosumming can be a matter of setting the rules so that something needlessly becomes a zero sum game. It can also be a discursive act of dichotomism or narrativism, portraying something as if it were a zero sum game when it actually isn't. One way of doing this is the argument that people shouldn't care about a certain issue, because there is some other issue they should care about. As if it wasn't possible to care about both issues. This argument can be used against all and any activism, because there is always some other issue that one should also care about. Another way is the argument that it would be inherently “selfish” to be honest about one's religion/belief or sexual orientation if it differs from the preferences of the parents or of mainstream society, arguing that refusing to live a lie would be at the family's expense. As if relatives would be inherently incapable of adapting and accepting their loved ones for who they are. (In Swedish: nollsummeri)
When applied to a category of human beings (in relation to another category), this is a facet of categorism.
