Abortion and adoption

One popular argument for abortion goes like this: prolifers are hypocrites unless they adopt kids. 

i) I haven't seen them turn that allegation into an actual argument, but maybe I missed it. Is the argument that if more prolifers adopted kids, that would save lives?

If so, is there any demonstrable evidence that abortion rates are correlated to adoption rates? Mothers who contemplate abortion already have the option of putting their child up for adoption. Is there any demonstrable evidence that mothers contemplating abortion think, "If I knew there was a Christian couple waiting to adopt my child, I wouldn't abort it"? 

ii) I don't know the stats, but it wouldn't surprise me if Christians adopt at far higher rates than atheists.

iii) It isn't necessarily hypocritical to value life, yet not do everything you can to save lives. For instance, driving cars inevitably results in thousands of fatalities every year. Does that mean it's hypocritical to say you value life if you drive a car? 

iv) Sometimes people have prior obligations. Take a grown child who's the caregiver for an elderly parent. They're not in a position to adopt a child. They already have a full plate. 

iv) What, exactly, is the general principle which the allegation of hypocrisy exemplifies? Does it go like this: "It's hypocritical to oppose something unless you're prepared to take up the slack if you're in a position to do so"?

If so, is that a valid inference? Is that a reliable principle in general?

Is it hypocritical of me to disapprove of people who litter unless I take it upon myself to dispose of their litter?

Is it hypocritical of me to disapprove of shoplifters unless I personally reimburse the store for stolen goods? 

Is it hypocritical of me to disapprove of people who release dangerous reptiles into the Everglades unless I adopt the dangerous reptiles?

v) It's not hypocritical to have public policies that incentive parents to raise their own kids. As a rule, kids are better off with their biological parents. 

vi) In addition, it's not hypocritical to have social policies that incentive people to be responsible, productive members of society rather than freeloaders who expect others to foot the bill for their lifestyle choices. 

vii) Nowadays, you have secular progressives who lobby to prohibit Christian adoption because Christians repudiate the LGBT agenda. They are closing down Christian adoption agencies. 

Are they going to simultaneously say prolifers are hypocritical for not adopting more kids when they turn right around and prohibit prolifers from adopting kids?
