The rightwing propaganda machine does its job to normalize his bullshit lies.
One doesn't have to listen to opposing views to be annoyed by someone.
The point the two people in your quote are saying is that the left is being so annoying that many will either not vote or vote right just because of how annoying the left is. The right is winning by not being as annoying as the left.
I'm sure you heard the talk during the last election, where everyone said both candidates sucked and if they were voting they would be like "the lesser of the two evil" or whatever. That is what they are saying. They are saying that the republicans and Trump will win the following elections because they are the less annoying people right now.
