> "They" may be more modern, if a little awkward in some cases, but the english language is fluid and thus "he", alongside "they", remains a perfectly acceptable for those who wish to use it in that capacity.
Well. I am not sure of your sources for your statements (1 to 3). But would love to read them, as this is a topic of great interest to me. Especially as they go against everything I did learn during my time studying the history of languages (German and English).
I know of language fluidity and I know of a time around the 14th century where "he" was in some contexts used in a more gender neutral way (and even that is debated nowadays). And even then the neutral "they" (singular and plural) was also in use in cases that were clearly gender neutral.
So looking back into the development and the history of the English language I cannot find (or recollect) indicators for your way of reading "he" as being totally fine and acceptable and really gender neutral (and not just a sign of a more patriarchal society).
Talking about fluidity of language. At least in the last some years there has been a development of "he" being incivil and assuming and therefore should probably not be used in a gender neutral way. Also that other alternatives would be more civil and unassuming regarding others taking part in our conversations.
> The message was able to be conveyed, which is the only requirement of the english language.
Well technically speaking that is true. But aren't there always human beings part of every conversation? And imho our wetware isn't a purely logic parser for information. We are flawed and our flaws should be considered when trying to communicate. Esp. if we try to get an idea across and not wanting to "hurt"/alienate others.
We have different "ways" we process information. The purely informational part of a message is but one of them. Ignoring the others might just hinder our arguments/ideas from getting the recognition they deserve.
One model of communication for example:
