I’ve been following the back 'n forth on this issue, not really knowing what to say. As with most all generalizations as to what “men” think or feel, there is a lot of variation. I find myself thinking - I do this a lot lately - of the historical context in which issues are joined. I don’t think there’s any doubt that traditional “masculine” roles and attitudes have been in retreat for around 50 years. I’ve said before I think we are living in a time of historical payback for inequalities which were direct results of male physical prowess since our kind first stood erect. This physical power was, obviously, a main source of control over others from family on up to kingdoms - as a rule (with exceptions).
Nowadays, I think, men are routinely denigrated as they have for several generations - in sitcoms, adverts, movies, most everywhere. Traditional male behavior in boys is being medicated out of existence as a form of psychopathology. A new myth has been constructed and is now unopposed. It begins and ends with “cis male, hetero… . Bad”. The responses of men I think, falls into three unequal categories. Some go along with it and happily voice their fides and mea culpas (perhaps in hopes of ‘scoring’); some just stay quiet and keep their heads down; some (likely few) take up opposing causes, like anti-abortion.
IMO, those who do the latter are exhibiting psych mechanisms in common with SJW’s on the left. Those latter get an actual rush from ginning up the real religious fervor of their (believed) morally superior cause and selves; the effect is augmented exponentially in mobs as evidenced by the wild-eyed, spittle-laced exhortations, ubiquitous among SJW’s. Naturally, such mob behavior - standard for the left - is impermissible on the right. This translates into police protecting pro-abortion mobs hurling invective and the occasional brick at the kneeling, peacefully and quietly praying anti-abortion protestors, who are arrested and prosecuted to the full extent of the draconian laws which have been passed to protect leftist sacraments. Some men may be seen on both sides.
This situation - the diminishment of men qua men - tends to limit (often self-imposed) men’s outward and visible political expressions. For a man who wishes to oppose the predominant leftist political orthodoxy, being vocally anti-abortion, I think is “caring so much” in the sense @Hypatia means. Here, again, we find ourselves having recourse to fundamental biological realities. Women live with the biological consequences of carrying a pregnancy as well as overwhelming nurturing biological instincts, which were and likely remain essential to the continuation of our species. Of course, saying so is a mortal sin in the Church of the Left (though my soul is not the only part of me in jeopardy for saying so).
These biological realities, I think, account for most men’s general distance from being ‘active’ as to the issue of abortion. Biological reality meant that, after insemination by an entity hard-wired to deposit sperm as far and wide as possible, the briefly-satisfied fellow went right back to hunting/gathering/fighting/planting/harvesting and little else until some powerful new software was installed to effect some new “wiring” in software; men’s aggression, for instance, was ameliorated. Their underlying interests and attention to things - not so much. To the extent men hold political positions - and history shows clearly - that passionate and transformative political advocacy, particularly that surviving in written form - was predominantly male.
In short, this long tradition of caring about fundamental matters political, I believe, is a pale remnant of earlier political activity and expressions of men - like those of the Founders. You may have noticed these great men put their “lives, their fortunes and their sacred honor” on the line for their moral and political beliefs. Maybe that’s why some men care so much about abortion. If you’ll pardon the pun, the biological status, the moral nature and the value of a human embryo/fetus/baby, is seminal to one’s understanding of humanity and construction of society.
