Nonsense.
It's not "hating" to consider something unimpressive, undesirable and unnecessary.
i "hate" on guarding for large presses and other machinery all day.
a little bit of common sense and some training go a VERY long way. many many people make it through their lives without needing unnecessary guarding and extra little help here and there from killing themselves or maiming themselves.
you will always find a case where something doesn't happen as it should and causes a problem that was unexpected, ie like kickback and things like that. but the solution to a problem that exists may not be the solution to the right problem.
some people say that every single saw should have a saw stop to prevent people from cutting their fingers off, and other people say the first thing somebody should make is a pusher or a "finger" to assist in using a table saw to prevent this very thing, it doesn't damage the saw and it costs considerably less. but these days the solutions to problems come at the cost of marketing. it is much easier (believe it or not) to market that the solution to a problem is a high tech and expensive invention that does the same job as taking 2 seconds to consider what you are doing, and using a tool to accomplish the job safely.
i put the pushers and material holders in the same boat as other tools like material grabbers with suction cups and magnets. you NEVER stick your hand inside a die while the press is running and not blocked up, but some places insist on having guarding in place to prevent people from sticking their fingers in a place that they shouldn't. so instead of teaching people proper procedure and usage of heavy and dangerous machinery, they attempt to block off any and all dangers and avoid telling them how to operate machines safely.
in my opinion this causes more problems. i'm just waiting for someone to "demonstrate" their stop saw and see that a fluke caused it to malfunction and they chop their finger off (or hand). the same that i see guarding fail around the plant. and people doing extremely unsafe things because they were never told how to operate a machine without guards (or improperly installed or maintained guards, think the scenario of an old mexican woman putting her gloved hand inside a small area to pick small sheetmetal material out while its still turning, and the wheel that flips the brackets over looks like a cheese grater. and she keeps putting her hands in there while its running, one day its going to get caught because the supervisors refuse to write her up and explain it to her about reaching in areas while things are running. thats a whole other issue, but a real one).
all in all. the answer is not more safeties, the answer is more knowledge and better operating practices. i would like to add that i would rather be sure that what i am doing is safe, than question it after something happens. if i have to reach into a press or other operating area, i will stop it, lock it out, and block the ram up so it can't come down regardless of how safe i think it is because i pulled part of the master start circuit out to prevent it from running or to prevent the brake from disengaging (even though most are supposed to stay clamped all the time). just the same that if i am cutting wood, i am ensuring that the path for my hands is clear and my work area is not cluttered and i'm not going to trip, stumble, or fall into the blade while working. i would rather sacrifice the piece i'm working on cutting than cut my finger off.
