The modern conservative, especially the tea party or Trump conservative, isn't a true conservative (and certainly not a Reagan conservative).
The reason I sometimes put "conservative" in quote marks when I speak about the US Know Nothing (LIterally) Party is because, indeed, they aren't really conservatives in any real sense.
Look it up: conservative is a relatively well-defined ideology (well, actually a family of closely related ideologies). Not only do contemporary American "conservatives" not fit any of these definitions, they don't even have a coherent ideology at all.
They are all just a bunch of angry white people screaming about stuff they don't like.
