My mom was the first born and then had two younger brothers. They were prized. She was tolerated. Her parents were from the OLD COUNTRY and I expect that view was standard normal typical. Methinks it may still be.
The bias against women is legendary.
The bias against people of color we see daily.
The bias against independent thinkers is obvious. They get poisoned imprisoned slaughtered.
When and where are those with that bias going to be BIASED AGAINST? Where is fair? Where is balance? Where is reciprocity?
