Those videos are of artic peoples who have adapted to a life that is mostly devoid of sources of vegetables and fruit or the ability to produce such sources and largely devoid of traditional materials used to make fire (though it should be pointed out that the Innuit do cook some of their meat and other food). While they may consume a lot of their meat raw, that does not make the Innuit the most practical or even the healhiest model for the rest of mankind.
I note that the third video showed people eating uncooked walrus - but it had to first be buried for a full year in the permafrost in order for it to decompose enough for it to be eaten (and it stated that decomposition had to be managed carefully to prevent it from turning into a toxic jelly). I don't think that they guy who made the video could be described as "having a great time" eating the decomposed walrus - more like having a very difficult time holding it down.
I don't think it is a matter of merely being "too civilized" to eat raw meat but also one of being "too practical" to eat raw meat when their is fire and heat available to make it more edible. Surely no one would describe people of 200,000 years ago who used fire and heat to prepare their meat and meals as being "too civilized" to eat raw meat.
If you want to eat raw meat, that is fine with me. But I would propose that eating cooked meat is not a practice of modern civilized society as much as a continuation of hundreds of thousands of years and that the raw omnivore movement of today is actually much more modern in concept than what we have normally adapted to do over the ages.
Well, gotta run and check on the vegetable and meat stew I am making for today's fare . . . trust me, it is a time honored tradition.
