Since contraception was introduced and accepted en-mass it has increased abortion rates since now sex is viewed as separate from getting pregnant.
That is a correlation in time, not a correlation in cause.

It’s not about a contraceptive mentality as the primary cause; it’s about a fornication physicality and a promiscuity physicality (and mentality) as the primary cause. The separation is between sex and marriage (or commitment to marry), between sex and genuine, committed, permanent love with responsibility (i.e., marriage).
And again, your statement above is not supported by statistics showing an opposite relationship between contraception and abortion in countries or clusters where contraception is heavily & consistently applied.
There is no social unit being envisioned, so i.m.o. you’re right in a very indirect or tangential way, in that there is no intertwined connectivity: sex/committed love/ intended marriage choice /logical reproduction proceeding from those intertwined bonds/ commitment to society, i.e., the social unit (man-woman-child). Sex is dislocated from that entire holistic dynamic of that and is nothing more than any other physical pleasure, disconnected from relationship (man to woman, woman to child, parents plural to child).
Yes, indeed, sex is seen as separate from childbearing, but that is true among the unmarried. The same age groups most likely to have abortions (age 20-24, then age 25-29, then age < 20) do so dramatically less when married
but still using contraceptives. Therefore, contraception
per se cannot be seen as the pivotal “reason” for abortion.
Also, the pill is an abortifacient since it has been scientifically proven that you can still ovulate and have a fertilized egg but it does not attach itself.
That has nothing to do with “leads to” abortion. That has to do with
is an abortifacient, as opposed to “leading to” (or “causing”) a surgical procedure by a third party.
Also, many women conceive on the pill and choose to have an abortion since they were not planning or ready to have a child.
They don’t do that with any greater frequency than do women who were relying only on barrier methods. If they’re in no position to raise a child single-handedly, which is expensive in this country, they are very likely to seek an abortion, no matter what method of contraception they have been using.
This is a country which discards relationships, and sadly sees that as “freedom.” It’s really a selfish “freedom” (without responsibility), a freedom from attachment. Without a unifed national policy & promotion of effective and comprehensive contraceptive use (which I’m not advocating!), the natural result of discarding such relationships is to discard the biological product as well: that is just one more logical detachment from relationship.
