I was born in the early 70s, so by the time horror films were available on video to the masses, I was pretty much old enough to make my own mind up about watching them (my tastes have never inclined towards gore type films, even now in my 50s, I take my glasses off if a scene is getting gory so I can't see it).
I suspect even my parents would have drawn a line at my watching the films you mention when I was a small child, had it arisen! But my viewing was limited to the offerings of BBC1, BBC2 and A.T.V.
