That question is no different than if you were asking how do you stop murder?
You stop murder by not committing it yourself. You stop abortion by not committing it yourself. That’s the only power you have - unless you have a greater and actually workable civic plan.
I see people here complaining all the time - but all they do is post inflammatory stuff, with no instructions as to how we can actually end this through a peaceful political process.
I guess that’s too hard and complicated. It’s easier to do the ‘Christian’ version of virtue-signalling.
