Furthermore these laws almost exclusively apply when speaking about specific people. QAnon people can be sued if they say "Hillary Clinton drinks the blood of children". However they are safe saying "Democrats drink the blood of children." I don't understand why these two should be treated differently from a moral, ethical, or legal perspective.

Also these are largely viewed as civil issues and not criminal so Hillary Clinton needs to take them to court and not the State. These two issues combined basically give Americans free rein to make up whatever lies they want about whatever group they wish to defame.
