If it seems like SJWs are on overdrive the past few years, it's because they are. They weren't supposed to go full retard, they were supposed to provide a slow temperature rise to normalize everything. But when Trump, and the forces behind him, were recognized as a viable threat (probably late 2015?) they started amping it up. When he was the nomination, they went full blown ballistic.
Why? Because theyre losing and they recognize that this is the desperate attempt in enacting their horrible, nonsensical culture of self destruction.
