The M70 safety locks the striker and disconnects the trigger from te process. Some will prefer this, and some don't know and or don't care. For those don't know and don't care there is the option of continuing to not care. No real downside for them.
Some people want the bolt handle locked, some want it unlocked. Some want it locked most of the time, with the option of unlocking for unloading. Since those who have thought about it enough to have a preference can use the safety their way, everyone is covered so everyone should be happy. Those that don't care are in more of a neutral state. For the unknowing, opinions separate drastically. There are those in the "ignorance is bliss" camp, and others flying the "what you don't know can't hurt you" banner. Theiy intermix freely, and have been known to exist in the same litter. A third faction is the "don't cares" they do recognize the they are different than the first two groups but not surprisingly don't care. They are also a cheerful bunch, unless provoked.
Next up is the "do know and do care". They are aware that ignorance is bliss, but believe that what you don't know can hurt you. They might be happy, but only if they send missionaries to the first two groups.
The final study group is the "we're not happy until you're not happy" group. Not surprisingly the safety that gives everyone what they want and need , with different modes of operation infuriates them. They are widely known for unprovoked charges, and the colour red drives them into a rage. This was to be a further field of study, since the discovery that they could only see things in black and white. Unfortunately the study grant was exhausted getting through the grey area.
