This website seems hard to me. Always getting down votes. It's highly degrading me. I am frustrated to use this website. I won't post comments or discussion or questions in this website. If I ask questions they are always down voted and so are my answers. This site won't help beginners, I think. I also want to mention another thing: tags, which are extremely disguising things, and also reputation. So that I am tagging here
You are very right in drawing that conclusion.
However, this site was never meant to help beginners! It is clearly stated that
English Language & Usage Stack Exchange is a question and answer site for linguists, etymologists, and serious English language enthusiasts.
For beginners, people that are learning the English language, there is our sister site: English Language Learners.
The Internet is full of people from different places, different cultures, and different age ranges. Stack Exchange is also a part of that, having a very wide variety of users, some/most of who are here to prove/approve themselves and disapprove all the others out there. This behavior will be more tangible when you're new to the place and the others with a higher reputation, feel they have more authority. This is not a good thing, but that's how the world works nowadays! We need to be able to believe in our own abilities, and try to improve them in a good way.
This website can have negative effects on the new (or even old) users, but at the same time it helps them grow up, and mature to be independent learners, being able to search, research and learn independently.
As @oerkelens mentioned, you should ask your beginner questions in E.L.L., but chances are you'll get burnt over there, too. I was looking at your profile, and I noticed you had an answer that provided two links only. You do get down-votes for that, because there's no content other than a link; and in case the contents of that link changes in the future, there will be no valid answer for the question on Stack Exchange, so if you want to provide an answer, you must explain it in detail and add the reference to it in your post.
Or, a question of yours has been put on hold as unclear what you're asking, since there are no actual questions in that post. You've thought about a person and tried to describe her in two lines and a subject line. We cannot guess what you're thinking about. You should express yourself clearly to get a good answer.
Also do not forget that all the users get here for the effort they put in answering questions and maintaining the site, is reputation (+badges), they're not paid to maintain such a service, so there should be a rewarding system to demonstrate people's activity, and there's nothing wrong about that. If you think that reputation and tags are disgusting/disguising (?) you shouldn't be bothered at the down-votes that you receive.
Try editing your posts and adding more context to them, and voters should remove their down-votes. However, there are people who enjoy being sarcastic and mocking others in addition to trolling, and find the Internet and these websites a great place to do so. This shouldn't hold you back, because as I said, different people are different in many aspects and you see this in real life, as well. Do the right thing, flag and report the irrelevant content, and eventually if you're still getting harassed for any reason, flag the related posts for moderation attention, and they'll take care of it, if it's a rational report.
