Did he say he liked GWTW, or did he just ask where American-made classics like GWTW are being made nowadays? Most of those yelling “racist” worship Hollywood and probably liked GWTW until the minute before he brought it up.
It’s not a favorite of mine, but one would have to be deliberately obtuse not to recognize its status amongst movies in general.
You are forgetting that we are dealing with people here who think we need to tear down our statues and monuments and artwork because they were made in racist eras.
These people hate our history. And destroying it is their way of reconciling with it.
