This is probably one of the more tragic results of the mess we’re in right now and there is no good solution. Not killing anyone would be ideal, but not enough people feel that way or we wouldn’t be killing each other as much as we do.
You can’t change a bigots heart unless they want to change. You could kill them, but what difference would there be between you and a bigot at that point? These kinds of problems take generations to sort out, which is unfortunate for all the dead southern queer people who will be murdered legally in the years to come.
I set my mom (62) up an old laptop running Ubuntu last year when her laptop was stolen out of my sister’s car. She’s adjusted fairly well to it. She needed a lot of hands on support at first and any time she uses her printer, but she has figured out how to do a lot of things on it on her own.
She makes papercraft activities in inkscape for a weekly storytime she hosts at a bookstore and has gotten very proficient, but still needs some hand holding when printing errors crop up.
