I dont know what "based" means 
They hate libtardz and love "freedom" so they are OK in my book.
'Based' has a few different slang meanings but I've always interpreted it to mean something along the something along the lines of "based in reality".
Like if someone says men can't be women, they're based.
Or if they're honest about crime demographics, they're based.
If someone defines abortion NOT as a "choice" or "reproductive rights" but as what it really is, they're based.
It basically means stepping outside the media programming and not being influenced by, and not using, their word magic.
(Below)Bill Burr being based on abortion: Burr is pro-abortion but he's 'based' on what it is.
