Biology is stronger than Sociology

In a functioning democracy, freedom of opinion and freedom of science are just as important as open discourse, unencumbered by censorship, different opinions and dialectical friction. But these democratic achievements are increasingly under threat. For example, a doctoral student at the Humboldt University in Berlin wanted to give a lecture on the topic of bisexuality on the occasion of a "long night of science". The topic was the biological fact that in the reproductive sense there are only the sexes male and female, only sperm and egg. This immediately provoked gender activists and gender activists. They threatened the student and the university with demonstrations and violence. As a result, the university cancelled the lecture for "safety reasons" in the sense of "visitors".
