Abortion is not equivalent to other social issues of our century.
It's not comparable to poverty, not comparable to gun violence, not comparable to GMOs, not comparable to vaccination, not comparable to energy crises, not comparable to environmental issues, not comparable to taxation, not comparable even to racism or sex trafficking. It's in a category of its own. That's a pretty big claim, I know, but it's only a sort of social illusion, a kind of stupor of dehumanization that makes it necessary to say.
Why is it not equivalent? Because abortion is:
1.) Killing an innocent human being. (There's a one-word summary for that: murder.)
2.) Legal. (It's publicly instituted, approved, protected, and supported.)
Abortion doesn't sometimes result in murders, or possibly result in murders, or arguably result in murders, it's murder by definition and intentional, institutionalized, public, legal & protected murder.
You can make arguments over all the other social issues, attempting to show that they exist, that they have deleterious effects to the extreme of - at worst - murder, but of the ones that involve or amount to murder, they are not legal, and the ones that are legal are not directly murder.
I could add a third to this, which is a matter of scale.
Abortion is not a small thing, something that happens in a corner, here or there, some atrocity happening in dark corners of society. In 2014, the year of the "historic low" in legal killings of innocent male and female human beings, 926,200 victims' bodies were sent to incinerators or to laboratories for experimentation.

Oddly enough even many who claim to be "pro-life" (presumably because they believe it to be murder - I can't think of any other sane reason to oppose it) think this is a sort of "victory" where only 926,200 human beings who belong to a dehumanized class are murdered with the full approval of the state and of a sizable and powerful majority. Put any other class of human beings that haven't been effectively dehumanized in that statistic and try to think of it as a "victory". Still thinking of some other people group, try to think of anything short of its legal abolition & prosecution coupled with a general abhorrence for it by the nation's people as a victory.
It may be good news to a few, and bad news to many, but there is a God. He is just, and is no respecter of persons. Every child suctioned out, every little hand, foot and head dismembered, belongs to His creation, a human being in His image that has his attention, whom He identifies as your neighbor in need. It's a sobering thought that Jesus Christ will come again to judge us "according to what we have done" in such a case. Our laws reject these little ones, God's image and creation. Our people murder them with impunity in public institutions. The majority of our "righteous" defend them with halfhearted regulatory demands as something less than human, while even more don't raise their voice at all in protest for fear that their popularity might take a hit.
Abortion is a holocaust, an antebellum slavery-style abomination, a genocidal massacre, and a present reality. It is not the only evil that needs righting in our world, but it is our national sin, with a prominence greater than any other. To speak otherwise is to speak untruly.
