all sorts of things like this are alive and well... most people have a prejudice against older people without even knowing it. certainly a lot of people have prejudices against women, people of color, people from other countries, other religions, overweight people and SO many other things... and then there are the sexual things like being gay or bi, or trans - being into bdsm or being involved in group marriage are on many people's hate list, too.

it's amazing that most of us can live together at all :-(
