My estranged dad (MAGA) called me today. He has cancer.

17. I know you aren't asking for advice, but I was in a similar situation once.

I was estranged from my father for many years because he condemned me for marrying outside my race.

One day I learned through family he was in the VA hospital after having a diabetic coma. He wanted to talk to me.

I automatically refused, but my then wife convinced me to call him anyway.

Without going into details, we somewhat reconciled. When he unexpectantly died a couple of days later, I was a lot less conflicted than I would have been if I had refused to talk to him.

Your mileage will vary... but if I may make a suggestion, err on the side of kindness.
