It's because what we've been calling "conservatives" were never really conservatives at all; rather the communist left labeled libertarians conservatives as it sought to destroy them both.

This triggered fusionism, so the conservatives kind of went into hiding behind the libertarians. "Regain the freedom to say what we want first, and then we can worry about taking over." Now for some reason they've taken the mask off again even though they haven't been able to do that. I suspect they largely forgot their plan after fusionism took full effect, but now the recent unrest has led the new generation to rediscover the old truly conservative ideology.
