I don’t think that will happen immediately. There are many sexual orientations in line ahead of rapists, when it comes to the redefinition of marriage.
Next are homosexual men and women. They’re working on their link in the chain. Marriage will be redefined to accept all sexual orientations (what does it mean? that will be redefined too!)
Afterwards, there are those who think the number “2” in the definition of marriage is discriminatory against their sexual orientation, such as bisexuals, polygamists, polyandrists, polyamorists…those other sexual orientations are waiting patiently in line, waiting for the “gay marriage” thing to run its course. I think they’re the next group to demand “marriage equality” Multiple marriage will be next.
Where rapists stand in line, I have no idea. Probably after western civilization collapses in a century, radical Islam will take over and impose sharia law, allowing a husband to rape his wife. We already have that in many parts of the world. .
