I hate stories like this one. Look – the sample was of 46 (count them: forty-six) women aged between 23 and 83. Assuming an even spread of ages, only 5 or 6 were under the age of 30, which, I dare say, is an age group with fewer personal committments such as husbands or children that might rein in their more liberal attitudes. So it is barely surprising that 90% of those surveyed are quite conservative in their views.
Go away, researchers – come back when you have something useful to say.
