The same people making these laws get to determine what hate speech is defined as. You can be charged with a hate crime in Louisiana for resisting arrest at a peaceful protest, for instance. In Ireland you can run afoul of blasphemy laws, which is in the same spirit as hate speech laws (in my religion it's a blasphemy to discuss any other religion, and since Ireland won't enforce my ideas of blasphemy on anyone else, their enforcement is selective for their favorite religions).
Once you make it a crime to express certain opinions, all opinions are up for negotiation. It's not hard to imagine an ultra conservative getting elected and what that would do to discussion around LGBT, for instance.
I happen to own a paper copy of this book, and as usual for sharpening books, they throw in a chapter on axes as an afterthought. Sharpening an ax is different enough from most other sharpening that you should get a specialized text for it. It's not that difficult or terribly specialized, but knife sharpeners always seem to want to apply the ideas of knife sharpening to axes, which isn't quite right all the time.
Two books I recommend for axes are "One Moving Part", the USFS ax manual, probably the best (only?) work that they ever did:
And "The Ax Book" by Dudley Cook, which you'll have to buy a paper copy of. (I don't suggest you round the corners of your axes as he suggests though)
The old USFS ax manual, "An Ax to Grind", even had a companion video which you can find on youtube, though if you're new to sharpening the instructions could be more clear IMO:
