Labeling and criticizing my "tone" is just an ad hominem attackFactually incorrect. An Ad Hominem fallacy is suggesting that there is something wrong with you and that therefore your argument is wrong. You are entitled to any opinion you like. We celebrate iconoclasticism here, HN is all about people doing things most people do not like.
However, if you attempt to redefine the word "climbing" in a way that is entirely at odds with how everybody else uses the word, you can expect to encounter resistance. If the only climbing you respect is free soloing, have at it. I've free soloed, I respect it, I won't argue with that.
But if you're going to argue that everything else isn't climbing, well, that doesn't strike me as intellectually constructive. There is already an established vocabulary of terms for the various styles of climbing, and there is no visible need for throwing it all out and starting from scratch.
Now to address your second point. It's an important one, and a little research into climbing history reveals that this is a divisive debate going back over a century. Some people feel that risk is an essential component of the climbing adventure. Some do not.
There is a gymnastic pursuit that is carried out on plastic and on rock called climbing, and in modern times it can be carried out with little or no risk. So can cycling. You can decide for yourself whether it is worth doing if there is no risk of injury or death.
There is also a thrill-seeking or adventure pursuit carried out on rock and in high, cold places. Proponents seeking adventure deliberately place themselves in harms way through free soloing, fast and light alpinism, and through placing protection that is of limited utility. Risk is not a black and white decision, most adventurers manage their adventure to expose themselves to a perceived tolerable amount of risk.
These two pursuits are both called "climbing." If you strongly prefer the latter to the exclusion of the former, you are not alone, but you also aren't in the majority.
So your question of why not build an escalator is easy to answer. The escalator removes the gymnastic element of the exercise and for those who seek adventure, removes too much risk.
