You can't ascribe the annoying behaviors of terminally online SJWs to the party. Number one, the top down power structure of the democratic party very clearly did not endorse or participate in any "latinx" or "they/them" tone policing. Number two, not only that, the party even went so far as to promote Liz Cheney and other Lincoln Project conservatives at the expense of alienating the voters who liked what Governor Walz was bringing to the table.
There's just no serious argument to be made that (1) the DNC ever embraced SJWs or (2) this non-existent embrace of SJWs is responsible for Gen Z men moving toward Trump.
The scholars who actually monitor and research modern media have made a variety of observations and hypotheses, but one common theme is that the Dems basically ceded the online spaces for years, allowing a "Manosphere" to grow and take hold with that demographic, instilling toxic beliefs and misogynist, xenophobic values in them while they're in a vulnerable age. Dems arrogantly believed that they didn't need to put in any work, just like what happened with Latinos.
