I think a better title for this thread might be "A few honestly held opinions about DE shaving". Some are certainly not true for me.
After shaving for more than a half century I have come to the conclusion that......
Shaving is what you make of it.
No more
No less.
OK, to me those look a lot more like OPINIONS that "truths". I can agree with some of them, but I'd say, in my experience, numbers 1 and 2 aren't truths, those are lies.
Having shaved since the mid 1960s on and of with DEs I cannot agree with your list entirely. Shaving is as simple or complicated as you want to make it considering what works for you.

This is ALL TRUE, providing we all have the same face/beard/comfort levels and ymmv is just a B&B fallacy (perpetrated by people who don't realize we are all the same shaver, strangely with different names).
The cost of the razor means nothing as far as the quality of the shave.
My addition.
I agree. I brought up the point about a blade being as sharp and as smooth as it will ever be when it is new. Pretty much got laughed out of the thread.
As for canned shaving cream, you may even get a better shave if you are someone who struggles lathering soap with a brush. It is worse for your skin though.
Well obviously. You're not truly manly unless your stubble is so tough that it hones the blade while cutting.
