say I strongly believe that these propositions are true:
A
A → B
A → C
A → D
…
perhaps proposition A is that everyone deserves equal opportunity in life, and from that I draw B (open borders!) and C (public healthcare!) and D (antiracism!) and all kinds of other things.
now perhaps I can’t convince someone of proposition A, or I’m too gutless to try, so instead I construct alternative justifications and try to sell those instead:
X → B
Y → C
Z → D
…
perhaps proposition X is we should strengthen the country (by boosting skilled immigration!), and Y is that we should strive for efficiency (public healthcare!), and Z is that we shouldn’t make Jesus cry so much (fight racism!).
but wait, these alternative justifications might prove much more than I intended! investing heavily in the military might also strengthen the country, and clamping down on premarital sex might also stop Jesus crying.
or the implications may not be factual: someone might decide that actually the country isn’t strengthened by increased immigration, and then we have a pickle on our hands; by ceding our true motivations we’ve compromised our entire political program.
this doesn’t mean you can’t mention when a policy has multiple benefits, and something can be win-win on more than one axis. but it’s almost impossible to be a win on every axis and anyone who says otherwise is lying, although typically to themselves.
