Been around yes but the popularization of the term is entirely from low tier war hawks who think force and aggression and violence is a virtue.

No it's 100% these idiots pushing their fascist propaganda just like they tried to "rename" the Department of Defense to the Department of War. Most members of the military never even see actual fighting.

If you think a gender-neutral term used for decades within their own circles as a form of inclusive corporate-speak is "fascist propaganda" then I'm sorry to say you have serious issues.

When Hogseth finds out it's gender neutral he'll stop using it.

It is not a Trumpism. As an example, it has been on Wiktionary since 2008, well before Trump.

It’s been a term in rare-to-moderate use since the 1990s — Trump/Hegseth ramped it up to 11 and it’s every 3rd word out of Hegseth’s mouth because he thinks it sounds tough.
