Already There

There is good news for Kristen here:

1. Background checks are already the law. 

Now, there are no background checks mandated on a private transaction face-to-face. That would be unenforceable. Also, no background check must be passed prior to a thief stealing a gun. That, too, would be impossible to enforce. And the majority of "gun-crimes" are committed by persons who illegally obtained (i.e. - STOLE) the gun. 

2. Women already have full reproductive rights. 

Presuming a woman is capable of having a child, no law in the US prevents her from having one. Presuming a woman does not want to have a child, she has many methods of birth control from which to choose, including abstinence. Now, because the SCOTUS decision in Dobbs v Jackson, each state controls whether and to what extent abortion - the killing of an unborn child - is legal. Of course, abortion is not a reproductive right, nor is it health care. 

3. We already have a ban on state-mandated religion (It's the 1st Amendment). 

Now, this is not the famous Left-wing "freedom from religion" concept - but that is not "separation of church and state." Of course, even the phrase "separation of church and state" is completely absent from the Constitution. Also, it is important to realize that those who read this and scream about "shoving religion down their throat" are also the ones who follow religious persons or entities online and bitch and moan about the "shoving it down their throat" - despite following the entity on purpose! 

Summary

So, if Kristen's statistics are to be believed, then the majority of the US already approves of the way things are currently! (I'm certain that is not what Kristen wants to hear, though.)
