That happens a lot--with evolution, climate change, species loss, systemic racism, and so on.

This is why it's especially good to have comprehensive answers somewhere you can link to (or papers you can cite). As long as the answers actually address the question, it frees you to answer with nothing but a link, or a brief summary. Anyone who actually wants to get the deep answer can hear it, but you don't have to go to a lot of effort crafting answers for people who don't want to hear them. Anyone who only pretends to want answers gets an answer, and then can be called on it when they say something that is clearly not informed by the necessary information.

(But it does have to answer the question. For instance, if someone claims to be concerned about cis men pretending to be trans to be admitted to women's prisons where they will rape women, you couldn't answer them with a comprehensive analysis of the rates of rape committed by trans women. That would answer a different question--whether cis women are in danger from actual trans women.)
