People are right to say Dems are different when it comes to domestic policy, but they agree with Republicans on almost all foreign policy decisions. A significant portion of the criticisms Democrat representatives made of the recent Iran bombings amounted to, "Hey, you didn't give us a chance to agree wholeheartedly!"
And most of this "slide into fascism" is just taking foreign policies and applying them domestically. In that sense, Democrats hold a lot of the blame as well.
