Understanding the personality of Russians who support the war in Ukraine is one of the key steps to understanding how this war became possible. However, during the war, traditional sociological methods are not always applicable. Social media provides an alternative source of what is inside people's heads. In this paper, I compare the political identities, values, and interests of social media users in Russia who hold a strong position for or against the war in Ukraine. I collect data from VK, the most popular Russian social media platform, and analyze self-filled profile information as well as the groups that the users subscribed to. I found that proponents of the war tend to have a weaker political identity (self-identified as "moderate") compared to opponents, who specify it more precisely (often, but not limited to, "liberal"). Additionally, the values of the proponents more frequently align with those promoted by the Russian government, such as orthodoxy and family. Despite these differences, pro-war and anti-war users share many common interests, as evidenced by their subscriptions to the same groups focused on music, history, and sport. When asked to state the most important trait in people (a field users can fill in VK), the most frequent answer for both groups is "kindness and honesty". The analysis results, in addition to contributing to the understanding of public opinion in Russia, can be utilized for predicting one's position on the war based on their social media profile.

翻译：了解支持乌克兰战争的俄罗斯人的人格特征，是理解这场战争何以成为可能的关键步骤之一。然而在战争期间，传统社会学方法并不总是适用。社交媒体为洞察人们内心世界提供了替代性数据源。本文对比了俄罗斯社交媒体中对乌克兰战争持强烈支持或反对立场的用户的政治身份、价值观和兴趣偏好。我通过收集俄罗斯最流行的社交媒体平台VK的数据，分析用户自行填写的个人资料信息及其订阅的社群。研究发现：与反对者（通常但不仅限于明确标注"自由主义"立场）相比，支持者的政治身份更趋模糊（常自称"温和派"）。此外，支持者的价值观更频繁地与俄罗斯政府倡导的东正教信仰和家庭观念等价值取向相吻合。尽管存在这些差异，支持者与反对者仍共享诸多共同兴趣——例如双方关注的社群均涵盖音乐、历史和体育领域。当被问及"人类最重要的品质"（VK平台可选的填写字段）时，两群体的最高频答案均为"善良与诚实"。这些分析结果除了有助于理解俄罗斯舆论生态外，还可用于根据用户社交媒体档案预测其对战争的立场。
