  We have surveyed the optical linear polarimetric properties of 65 soft X-ray
selected ROSAT Active Galactic Nuclei (AGN). Most of these sources show low
polarization (<1%) and no optical reddening. This is in agreement with the
X-ray results suggesting a direct view on the center. However, two of our AGN
show polarization as high as 7--8% and high reddening. This optical reddening
suggests a high column of dusty gas, but why does this gas not absorb the soft
X-rays? We suggest that the dusty gas is actually ionized. There is evidence
for these 'warm' absorbers from X-ray absorption features seen in ROSAT and
ASCA spectra.
