SE.SE has long had (and still has) the problem that the relative percentage of bad, off-topic, too broad, and opinion-based questions is higher than on other sites, and that the absolute number of such questions is quite high in relation to the relatively small number of active contributors. In short, the individual contributor has to deal with more bad questions than on other sites.
SO, for example, has of course many more bad questions, but it also has orders of magnitude more contributors to deal with them. Plus, it has tools like the Triage queue to handle this, which we on SE.SE don't have, although we asked for it many times.
As a result, we try to do everything we can to make sure that visitors to the site only see on-topic, well-worded, well-crafted, well-written, well-formatted, specific, objective, interesting, answerable questions. In particular, we make sure that our homepage is a repository of examples of how to ask good questions.
The problem is that a homepage which is full of off-topic questions is both off-putting to people trying to ask a good questions as well as inviting people to ask bad questions (after all, they can always point to an existing bad question as an example of what exists on the site).
Questions that are down-voted disappear from the homepage. Also, questions that are down-voted are eligible to be voted on for deletion, which makes them invisible to users with less 10000 reputation points.
As a result of all of the above, down-voting of questions is somewhat more aggressive here on SE.SE than it is on other sites with less questions (where they have other means to effectively and efficiently deal with bad questions) or sites with larger communities (where there are more people available to distribute the load, and also people don't really go the homepage of SO, but people do visit the homepage of SE.SE).
These are special things that apply on this site in addition to what applies in general to the entire Stack Exchange network, which is that down-voting, closure, and deletion are not permanent and not the end of the road, but rather an invitation to improve the question, so that it can be undeleted, re-openend and upvoted.
This question you asked, for example, was completely and utterly off-topic because it had nothing whatsoever to do with Software Engineering. However, for this particular question, there was an even faster way than down-voting and deleting it to get it off the site: migrating it to where it is on-topic.
Your other question suffers from the fact that it is unclear, it is too broad, it hides crucial information in an off-site link instead of presenting it in question where it belongs, plus it even uses techniques which are typical of spammers and hides the target of the link behind a link redirection service. So, if this was my question, I would put all the relevant information in the question, including answering the question raised in the comments, narrow down the question to a concrete, focused, clear example, and try to define my terms better. For example, you identify as a root cause of your problems the fact that Python doesn't have "explicit type declarations", but actually Python does have explicit type declarations for many years now, so you need to explain a) why you think that explicit type declarations would help you, and b) why Python's existing explicit type declarations don't help you.
