Came to a realization that my opinions on abortion were based somewhat on false information

6. I'm wondering how one forms an opinion based on historical opinions.

"1) Abortion was always looked down upon in history by all societies.
 3) Abortion in America had never been looked at acceptable."

That "abortion has been historically frowned upon" seems a poor reason to be pro-choice. Why does historical thinking inform one's opinion on moral issues? Why, in fact, does someone else's thinking determine my thinking, be it historical or contemporary?

It was at one time considered acceptable to punish a thief by cutting off his hand. That does not in any way lead to my opinion today that such a thing is cruel and inhumane punishment. I am neither in favor of nor opposed to cutting off hands based on the thinking of other people. My thinking on it is based on my own sense of right and wrong.
