In 1982 an immigrant moved into a rental and there was a Stevens 20 ga break shotgun all rusty left behind. It was illegal for him to have a firearm and I got it for free.
The firing pin was broken.
I took it apart, looked at what was left of the firing pin, and made a new one with a framing nail chucked up in a drill while I attacked it with a file.
That nail firing pin helped me and others to kill birds and varmints with that shotgun.
The word 'forum" does not mean "not criticizing books."
"Ad hominem fallacy" is not the same as point by point criticism of books. If you bought the book, and believe it all, it may FEEL like an ad hominem attack, but you might strive to accept other points of view may exist.
Are we a nation of competing ideas, or a nation of forced conformity of thought?
