This is where part of "the hard part" is. It's easier than it first seems. The best thing to do is ask questions.
"What if he didn't really say that?"
"Can we just take the ideal and try to put it in place?"
There may be some time you realize that your own position has been shifted a bit by the media and some of the active counterintel on this and other media platforms.
Take immigration and the border. It would be great if we lived in a world where we could all just move where we wanted to live and be at peace in a productive/fulfilling life, wouldn't it? What factors stand in the way of this, both in terms of human nature, cultural divides, legal structures, etc?
For the time being - the crime must be stopped and order restored. These are not necessarily permanent solutions, but necessary stages to gaining a handle on a set of problems so that a long term structural change can be put into place that is wise to the success and failure of the past.
Why many liberals are confused on this point is that they are not recognizing the current problems. Disinformation campaigns have been floating the idea that there is no problem at the border and that it is purely bigotry and racism. If they are reasonable people and are willing to entertain the idea that they have been led to overlook a very real and present danger to our civilization, then they will likely understand that many of these policies are necessary to contain the problem.
A debate on what our immigration policy should look like is doomed to failure when one side is talking about what needs to be done to stop a problem and the other is talking about what it should look like in a world of rainbows and gumdrops.
Most people are good. Most people are reasonable. It has been through controlling perception of our world that the distinction between liberal and conservative has been created. Largely. There are internal and cultural biases that influence this - but if you put most people in front of the same, undeniable reality, they behave in a very similar manner to each other.
4% is a fucking huge number on a population scale, but is dwarfed by the figure of 96%.
