The "net positive"/"net negative", countervailing interest rationale (that's part of any prudent policy making) seems to go right out the window with regards to politically charged topics like this.
That becomes extremely evident when people put a spotlight and magnifying glass on each and every outlier incident that occurs to prove a point. (usually aimed at engaging in emotional manipulation and subversion). Rather than simply keeping the conversation confined to the merits (or lack of merits) of the policy itself.
Typically, you only try to manipulate and trick people when you know your argument isn't solid on its own.
If we weren't talking about abortions and laws that prevent ones in certain circumstances, and instead were discussing vaccine mandates... Would the "highlight every allergic reaction outlier" approach be seen as a good faith argument approach to discussing it? Or would it be dismissed as "anti-vaxxers trying to appeal to emotion and attempting to use the exception to negate the rule"?
Or if you want a completely apolitical example... seatbelts.
Per the CDC and the NHTSA
Last year, seatbelts saved 16,000 lives, and another 3500 that would've been prevented had the occupant been wearing one, in additional to preventing 80,000 serious injuries.
Flipside, for the same time window, there were 27 cases of a person getting trapped in a burning car by their seatbelt, and another 43 that got trapped by their seatbelt in a car that was immersed underwater.
If we were having a debate about new mandatory seatbelt laws, and I went out of my way to do an extensive emotional-charged write-up thread about each and every one of the 70 people who got killed by their seatbelt....
"They say Tanya was likely conscience while under water for minutes before finally succumbing and drowning"
and
"Witnesses say they could hear the child screaming in the car, but the child was unable to escape from the car due to the jammed seatbelt while the parents helplessly stood by crying and pleading"
What would the reaction to that be? Would anyone be buying that? Or would people say "c'mon dude, you just don't like wearing seatbelts and you're trying to manipulate everyone... seatbelts are an overwhelming net positive"
