You cannot just bin language though. It has to die a little with successive generations through lack of use or context. This is not just words that fall into disuse or are anachronistic but the grammer that rules the constructions of our language. While it is still useful, it will not disappear and is unlikely to be removed by dictat or force.
The same could have been said about other similar changes that have already happened, such as the removal of most of the rest of gender at a similar level in English. Or the removal of various other pronouns, such as "thou". Explicitly distinguishing between singular ("thou") and plural ("you") was more useful than gendered pronouns. What use do gendered pronouns have?
There is already clear precedent that, at least in English, pronouns can indeed be "just words that fall into disuse or are anachronistic". Just like other words.
I'd like gendered language to be removed from English. Not " by dictat or force" because, as you say, that is unlikely to work. I'm not l'Acadamie Francais

It could be made to work by dictat and force, but I think that the solution would be worse than the problem because imposing changes by dictat or force would require a dangerous degree of authoritarianism. So I'd like gendered language to be slipped into the bin over time, through lack of use. Because it doesn't have any beneficial use. It's only use is to promote sexism. More commonly, it's just used out of habit and without any meaning.
You're absolutely right - Let us step forth, good Engliscan, and remove all the offending descriptors that are based on people's appearances - No more colour, height, weight, sex, race, age or any of that silliness.
Why are you suggesting such a silly thing and why are you trying to associate it with me? It's your suggestion, not mine. I think your suggestion is silly and at best pointless.
Were you trying to make a reductio ad absurdum argument? If so, you failed. The whole point of reductio ad absurdum is that the argument it's being used against must at least potentially lead to the absurdity stated. English does not have different pronouns for people depending on their height, weight, "race", age or the colour of any part of them. There's no path from
my position to
your absurdity.
Furthermore, it shall also be a crime to refer to a ship as 'she', lest it cause much offense in a person.
I disagree with you about that too.
