Late to the party and a relative newb/lurker but I'll have a go:
1. "Touch typing" only means that you can type without looking at your keyboard. It has NOTHING to do with whether or not you bottom out. It doesn't mean you're gently caressing the keys on each down stroke as you would a virgin lover.
2. Everyone talking about how not bottoming out is the pinnacle of typing are just part of a misinformed cult who actually don't type for a living and therefore can spend their time "perfecting" their actuation distance rather than banging out lots of text efficiently.
3. People who say that MX reds are too light, complain about increased mistakes when typing on reds and say that keys frequently get depressed on accident when resting their fingers on the keys just never learned how to type properly.
4. If you don't know how to touch type at least 45 WPM, you treat mechanical keyboards as a weird fetish object rather than liking them for actual utilitarian reasons like durability and ergonomics.
5. The Microsoft Sculpt Ergonomic Keyboard is more ergonomic than any tenkeyless mechanical keyboard, even with its crappy scissor switch membrane keys.
