First of all, the people taking these actions don't perceive them as hostile, because they are not intended as hostile. I have no idea how to change that perception.
Second, the algorithm that blocked you was based on a time when downvotes were mostly reserved for serious issues, not the current environment where it's mostly a result of being unable to navigate this site's ever-narrowing scope. I have no idea why Stack Exchange hasn't made adjustments accordingly.
Third, people have unilaterally changed this site's de facto goals and scope, via voting patterns. 48.42% of people like you who ask questions disagree, but the site isn't structured in a way that your votes matter. I have no idea why Stack Exchange doesn't try to address that.
Finally, this site is also increasingly unwelcoming to people like me who try to be helpful and who view people like you not as spoiling the pristine quality of our curated repository of programming wisdom, but as honest seekers of help who are the site's most important visitors. My answers get deleted along with your questions. My votes are easily overruled. My posts are also often construed in the worst possible light. When people like me don't want to engage as often, that further imbalances the site's community moderation. I have no idea why Stack Exchange seems to be okay with that.
There have been efforts to try to address this problem, like this blog post and the subsequent cosmetic changes like the "Cap Baracudas is a new contributor. Be nice" notice at the top of this text box, but it has been mostly unsuccessful. Part of the problem is people feel demonized for using the tools provided as asked to improve the site's quality. I'll probably get a few defensive responses to this post because people tend to take my criticisms personally.
What concrete action would I propose? The moderation tools are imbalanced in favor of the downvoters, and there is not even a mild consequence for being unwelcoming. There should be more ways to trigger a temporary block on downvoting and closing, perhaps by enforcing a minimum ratio of positive moderation actions to negative ones. Maybe closing should get more difficult when the closed percentage surpasses a threshold. Maybe people should be able to get notifications when questions they've engaged positively with end up closed. Cosmetic changes won't change the perception of this site as hostile and unwelcoming.
