Very good list with all the reasons !
I’ve not seen 'China 9,liberty 37’
All the other ones i’d agree,albeit i’ve to watch ‘Comin at ya’ and ‘Fasthand’ again.
‘Sonny and Jed’ i’m not sure,it’s not very violent,but the way he treats her is really to spew.
By the way i dont like the whole movie,is Corbuccis worst.
Django,Blindman,Shanghai Joe and the other guys deserve the 18 rating still today
