That indicates a desire to boost population growth, not necessarily an ethical objection to abortion - I do think you’re absolutely correct about a fair portion of those politicians and donors but there’s still a large portion that I think are just using the movement for points.
There would also be more efficient solutions to this problem if that was their primary concern - we’d like see more focused attacks on Loving vs. Virginia if it was specifically racially motivated (rather than “American culture” motivated)… and even then I think the best approach would just be super-charging child tax credits and potentially introducing childless tax penalties.
I think my original statement was overly simplified, though.
