They can.
When it comes from people changing from being dickheads, I think it can take some people rock bottom, or being confronted by a chad who they perceive as worthy of respect to change to change them.
My mom is/was a racist Trumper, until my chad uncle confronted her and told her she was being a dick. He told her that he wouldn't continue to talk to her if she didn't change.
She did take heed and ended up not voting for Trump in 2024.
Most people who are like my mom won't listen to somebody like me. She sees me as not worth listening to because I'm not a man.
And this is why I think only a recovered narcissist male who has seen this happen in real time (and who is also a chad) will probably be successful as an opponent against Trump.
I have a towel rotation. I use a towel for a couple of showers then it will go on the floor for a couple of days. Then into the wash.
I have had bath mats before and they have all gotten pretty gross or end up getting thrown out after a while.
