If you can't make the argument logically all you're left with is force. Once the left gained ascendancy they couldn't hide behind the equal rights schtick. Their argument was always 'we just want the same as everyone else and to be left alone.' Most people were fine with that and from a secular world view it makes sense.
Now they just want to control everything and end civilization - but they are still using the same old 'Leave us alone, don't be mean arguments." That doesn't hold. They have no argument, so force is all they have.
More to the point, they have no argument, and they know it. But they still want all the power. All they can do is name call, bully and censor. Welcome to the world of echo chambers. They know their position doesn't make sense logically - but with enough dead bodies they can prop their ideology up.
