Everything humans do is political. Thinking something is not political is like thinking you don't have an accent: it just means you think of the politics as normal, not that they don't exist.

The practice of science involves choices about where to allocate resources, what lines of research are considered prestigious, what fields of study are encouraged or discouraged, debates over the ethics of technologies that arise from research, who gets to do the science... All of these considerations and more are political.
