“Can you provide any contemporary poskim who rule that toeiva marriage must be illegal? Why would a posek today rule that, which is obvious, when no government will be taking their direction from poskim. Same with women’s suffrage.”
Just so I understand you correctly, are you saying that any contemporary posek would want toeiva marriage to be illegal, but once the government rules it legal, then it is ok for an individual to get toeiva married?
Otherwise what is the connection to women’s suffrage?
