You can question whether it is "alive". But a fetus is unquestionably not a baby, or else the word "birth" has no meaning, and I doubt even the most Pro-life of pro-lifers will ignore the physiological differences between a fetus and a baby.
Birth doesn't make it a person. It's not an either-or meaning. To the extent that "birth" has been used to indicate the beginning of life, it is a result of ignorance and an inability to ascertain life. In any event, birth is seldom used to connote "creation". More often, it's the start of a new stage.
Also, if you are going to link contraception and abortion, you'll have to find some evidence that the opposition to either supports casual sex. Those who support promiscuity and oppose abortion are generally contraception enthusiasts.
And no. You don't get to demand the public fund practices they find immoral (as all but the most socially-conservative are not trying to outlaw contraception, the issue is almost always the public funding or subsidizing of contraceptives) by suggesting it might lead to fewer homicides. The onus is not on decent human beings to appease murderers, it is on the murderers to refrain, in order to avoid the harshest punishment.
Because you don't have a logically consistent bone in your body, and you have a habit of refusing to believe people's positions are what they say they are. The position of the mentally-functional opposition to infanticide is that a human being is entitled to the full legal protections of all human beings, regardless of its stage of life, and that a fetus is a human being, no less and no more. No one opposes government intervention to save lives. Most of the pro-life crowd was demanding President and/or Governor Bush intervene to save Terri Schiavo and their failure to do so probably contributed heavily to their loss of Congress in '06 and the GOP nomination in '16.
Because you would not find any answer satisfactory, I suspect, given your multiple attempts in this very post to link unaffiliated issues or phenomena.
