You are dealing with multiple simultaneous effect coincidentally, and you see only their sum.
- Many of the newbies have major problems, not with English, but with literacy et al. They can't formulate a single sentence, they don't use capitals, punctuations, while it is clearly visible that their English skill is far enough for them to do it.
- Most of the newbies are not only newbies in the IT, they are newbies in the communication, too. They are simply incapable to understand, for example, that we aren't a "wonder machine" seeing everything on their machine and understanding all of their thoughts.
- Yes, also an irrational hostility exists. It targets mainly newbies, but everybody gets a little from it. For example, recently I've made some Go questions (I have 4600 rep and 10+ golden badges on the SO). Nearly all of them were downvoted. In one of them, I've got also some close votes with "go to the SU" reasoning. Why? I have no idea. My impression is that somehow a "community" were collected on the SO around Go, and this community has an irrational, collective urge to exterminate all the Go newbies. I think you could have faced some similar in the C++ area now.
The evil is mainly an irrational thing. Doing harm, because it is needed, or there is no other option, is not really evil. You can understand it, you can deal it, you can handle it. Even if it is harmful, at least you have something to think, something to do. There are ways of a compromise, there are ways to adapt.
In the case of the pure evil, you simply can't see or can't understand the reason. Because there is no reason. It is a l'art pour l'art thing. It is an esoterical thing.
I've tought on a possibility, that I start a new account, from which I only make my questions. If you separate your questions into a secondary account, and thus you have only answers on your main account, then your main account will be exempt from the problem, that you can't delete even your own downvoted questions. This can be done legally on the rules of the SE (until you use your different accounts to support eachother. I.e. not only voting to your own posts is forbidden, but any self-supporting activity, for example writing supporting comments from your alter-egos). There is also a danger, that your new "question-account" gets a question ban. If it got, it would be a misuse to post questions from any of your accounts.
