If the separation of the blinds is small then light will not be able
to vibrate in that direction. Hence the light passing through it is
polarized. This efficiency is dependent on the blind separation as
compared to the wavelength of light.

So are you saying then that the waves that are vibrating parallel
the lengths of the open "slits" are the ones that get through?

If so, have you looked at the wikipedia article on this?

"Note that the polarization direction is perpendicular to the wires; the
concept that waves "slip through" the gaps between the wires is incorrect."

Wire mesh is made of ectrically conducting material.
A horizontally oriented slot antenna radiates vertically polarized.
Think of the wire mesh as an array of slot antennas.

Dielectrical antennas made of insulating material
react the other way round.
Think of the plastic molecules as dielectical slots.
