What I mean is, a truly pro-life person wouldn't argue "Its ok for cops to shoot minorities because you get so many abortions." That would be hypocritical and foolish.
Yet here we are
Huh. It doesn't seem to me that anyone is arguing that it's ok for cops to kill black people because they get so many abortions. "BlackLivesMatter" seems like a perfectly appropriate twitter handle to mention the unprecedented black genocide by abortion. When talking about the value of black lives, why are we only allowed to talk about that in the context of police shootings?
The basis of those tweets seem like they are saying "You say black lives matter, yet you get tons of abortions, so shame on you" instead of "Black lives matter, lets work together to prevent mistreatment by police, and provide ways to give minorities better options during unplanned pregnancies"
Ok, so even if their point was, as you say, that "You say black lives matter, yet you get tons of abortions, so shame on you" - that's a far cry from saying that it's ok for cops to kill black people because they get a lot of abortions.
As for the "better options" crap - poverty is not dependent on skin color, and everyone has the same options: you have the kid and take care of him/her, you have the kid and give him/her up for adoption, or you kill the kid. Two of those options results in a living baby - the other results in a dead baby. It's quite something to argue that "we'll stop killing our babies when the government gives us more money!"
