Y'know what? I looked up her organization's site, hoping to find arguments. Here; Students for Life of America; https://studentsforlife.org/learn/
Let's go over some of this;
Human Development: This is all both a straw man, and an appeal to emotion. Abortion rights are about bodily autonomy, fetal personhood/development does not matter, and it is only brought up in a dishonest attempt to appeal to emotions. There isn't any possibility of any fact of human development swaying a rational person's stance on being pro-choice. It's not relevant.
Abortion: There's a whole metric fuck-ton of intentionally dishonest and vastly-debunked propaganda horseshit against agencies like Planned Parenthood in here. It's all lies.
How to Defend your Stance: This section goes topic-by-topic, and it's all manipulative tactics rooted in apologist strategies, pulling bullshit like citing context-free "facts" framed in an alarming manner and hoping you can trick your target's emotional responses and short-circuit their rationality. There's a lot of talk about "changing hearts", which is entirely about emotions. There is no attempt to produce a rational, science-based objection to abortion, it's all just separated and manipulative framings that don't approach the subject honestly.
If this lady and her folks were honest and had a valid point, they'd be able to present a rational and science-based explanation for why no one should support abortion rights, where if you agree with each premise in turn (each premise being incontrovertible science-based fact), the conclusion necessarily and inevitably follows. They can't, which is why they don't even try. It's all just piecemeal trying to cast doubt on specific components of the pro-choice argument(s), none of which actually land but might convince a few who allow themselves to be confused by the emotional appeal of wringing hands and crying about "babies".
I feel insulted that you thought any of this was legitimate counterpoint. Absolutely insulting. This is bottom-tier garbage that only pro-lifers find convincing in the first place, and none of it's new information to the discussion.
