(Disclaimer: I'm a moderator here, but this answer is not an Official Moderator Team Response - it's just my personal response, and I haven't discussed with the other mods before posting it.)
As a site and community, Literature SE welcomes answers from anyone, regardless of cultural background. We try our best to be understanding of different cultures and ways of thinking, and to embrace literature from all around the world. I won't say we're perfect - our content is still biased towards English-language and other European literature, which is unsurprising given the typical userbase of Stack Exchange sites - but we do try. This isn't just an empty platitude: we have a topic challenge programme specifically designed to increase content and participation related to literature from different parts of the world, especially from non-English and non-Western cultures. (You mention "White", but I don't know what someone's skin colour has to do with culture, language, or literature.)
Another thing to bear in mind is that voting isn't personal, and a single vote doesn't mean much. Your answer currently sits at a score of -1, which means that one person found it poor enough to be worth downvoting. Whatever the site culture may be or aspire to be, we can't control every single user and their voting. Upvotes and downvotes are mostly each user's own to do with as they see fit. And certainly, the downvote wouldn't be related to what culture you come from, as nobody can even guess that from the name "user2450223".
This site (and Stack Exchange generally) expects answers to be backed up by something, whether that's a reputable source (i.e. not something like Wikipedia that random internet people can edit) or a solid rational argument. One-sentence answers are usually not well received, as it's hard for anyone without the same knowledge to judge whether they make sense or not. Remember, we don't know who you are or where you come from - even if you have real expert knowledge, a one-line answer is still a one-line answer from a random internet person, unless your knowledge is shown in backing up or explaining the answer.
Check out How can I write good interpretation or meaning answers?, a meta Q&A posted by a former mod in an attempt to give guidelines on quality posting at Literature SE. Part of it quotes from the How do I write a good answer? page in the Help Centre, but that's SE-wide and much of the meta post is Literature-specific.
