Fertility Gap

...College studies of the social behavior differences between conservatives and liberals have shown that out of 100 adults, conservatives produce 208 babies, but liberals produce only 147 babies. If children are influenced to think politically similar to their parents, then the conservatives are multiplying their influence by having more offspring.

...The analysis conjectured that the liberal agenda of pro-choice in pregnancy, and same-sex marriage, might contribute to a smaller reproductive rate. Also, city dwellers tend to be more liberal and also to want smaller families.

...Thus liberals cannot grow their influence except by trying to convince other people to change their beliefs by being more broadminded. Tolerance becomes a catchword for their proselytizing the populace.
