Until I’m proven wrong I’ll assume Roberts, Alito, Scalia and thomas are all pro life.
I agree that Scalia, Thomas, Roberts and Alito are probably pro-life. But, as Scalia constantly tells us, it is not for the justices to define this, but for them to determine which laws are constitutional and which are not.
Being strict constructionists, they should only judge the constitionality of the laws. I suspect that if Roe vs. Wade is overturned, They will all accept that each state can define it’s own laws. I also suspect they would accept as constituional the right of any state to declare the sanctity of life and to define protection from conception to natural death.
