That's not going to be an issue. There are zero such beings known so far, no hard evidence they even exist, and we're not going to find or create ones any time soon - the same people who engage in language policing also currently dislike space exploration for various ideological reasons.
Well the colonizers didn't know that Native Americans existed before landing in America, and look what happened. We must prevent any and all such occurrences in our interplanetary future by only using a non-specieist vocabulary.
It’s so obvious that if colonizers had used inclusive language, everybody would have lived in peace. Though maybe labelling them ‘colonizers’ and not ‘welcome guests’ was only the first of a set of micro aggressions that precipitated the situation.
You have no argument there. The same people who care about butchering language and destroying society are the same people who don't care about facts or what's real.
