Michael Rosenfeld, a sociologist at Stanford, shares how societies views on gay rights has been one of the biggest changes in history of public opinion.
In 1988, when the General Social Survey, one of the biggest surveys asked to people every year, first asked the question about same sex marriage, only 11.6% of respondents said that they thought same sex couples should have the right to marry.
By 2018, the number of Americans who said same sex couples should have the right to marry was 68 percent.
At first, survey researchers thought that what was happening with gay rights was only generational change. Younger people with more liberal attitudes were giving survey researchers different answers than older people with more conservative attitudes.
But when Michael looked at the data, he found lots and lots of people like William's parents, people who in a matter of years had fundamentally changed their outlook, even though it was sort of Democrats and liberals who were more likely to be open to gay rights.
It turns out that there were plenty of evangelical Christians, rural people, Republican voters who actually changed their mind on these issues. Tens of millions of people believing one thing and then like a light switch being flipped, believing exactly the opposite.
That almost never happens.
