I believe there are JW-like behaviors on both sides of the "ex-JW aisle" when it comes to politics. These observations I have noted before are not an "I'm right, you're wrong" statement. Just an observation I've noticed.
I realize there are some non-JWs that do this same thing when it comes to politics, but my observation still stands. It is very black and white thinking, so matter what your background, that we should all try to avoid.
To label any politician as all good or all bad is not even reasonable. I struggle with this myself when it comes to Trump. Forget his actions as a president (which I also have some problems with), I have trouble getting past his substance as a person. His attitude and behaviors towards other people he doesn't like or agree with is just egregious. I am sure Trump has some redeeming qualities that are not apparent in his public persona, and every once in a while I see them. Very, very rarely. I am still looking, though.
