The extension of their arguments is firstly that women who wish to avoid the risk of being charged with manslaughter or murder in the wake of a miscarriage must abide by behavioural guidelines which are contrary to science. i.e., to rest indoors anytime she may be pregnant.
The intended effect being to remove women of childbearing age from the workplace & from public life.
Secondly: to severely undermine reproductive healthcare, such that clinics shut, specialists flee, research is stopped & general knowledge regarding reproductive health & access to care plummets.
The overarching ideology being the production of new labourers & to increase desperation, so that Capitalists can avail of ever-cheaper labour in order to lure factories to set up in the US. This is the endgame of "bringing back our jobs" + anti-abortion rhetoric.
Going to come back to this to reflect in more detail to your original post and to this comment, but wanted to quickly float the idea that perhaps these people view you as particularly sound, so when they lay things on you or are just more emotional or intense in front of you, and you seem unphased - neither rushing to condemn them nor scrambling to reassure - they interpret that as disapproval from someone whom they find sound. And that because they value your judgement & integrity, they get sheepish and awkward in the absence of a strong outward reaction, which in turn you interpret as them thinking ill of you.
Only suggesting this because have seen quite a bit of this between people, and experienced mild versions of both ends of that dynamic.
Not that it helps, if it even resonates, or provides guidance.
