I'm not aware of any birth control that is 100%,
But then even in life, not everything is 100%,
And I imagine there are situations which have a 'possibility of causing harm.
Though choosing 'not to have sex, sounds 100% that there will be X% chance to harm
. . .
Then again,
Driving accidents would be 0% if no one drove,
. .
Then again, again,
People can drink, and think the odds are in their favor of not having an accident, because of past experiences,
Drinking is a pleasure,
While driving is a necessity for many people in the modern age.
. . .
Of the man lying,
I imagine a number of people Pro Life, would see that as the woman not consenting.
I suppose there are people who also 'think themselves infertile,
Which again,
I imagine a number of Pro Life people, would see that as neither consenting.
. . .
Well,
There's 'still people Pro Life,
Who highly value humans,
Especially weak helpless children, (Though such words depend on what one see's the unborn as)
Hence the people who are opposed to abortion,
Even in the cases of rape.
While they may view the pregnancy as a great wrong,
They also view abortion as wrong,
And view carrying the pregnancy to full term and birth, as a lesser wrong,
Than to kill the child. (Again, use of child depends on persons perception of the unborn)
. . .
I use child, weak helpless children,
Because it is descriptive of perception and value.
I understand appeal to emotion can be a fallacy, but I forget why,
So going to Google that after I post this, but still use it here,
Because it speaks to 'why those people act as they do.
