several topics in different (and often within the same) subreddits
referred to similar themes, and that different subreddits may have
different opinions on the same topic. For example, consider the           Figure 3: Every subreddit can be expressed as a vector of

upon our reading, slightly differently).                                  similar interests will have a higher cosine similarity.
   Themes: Based on our reading of the topic descriptors and
sample posts, we manually merge similar topics and assign labels
to them. After merging, we obtain 24 topics, which we refer to as
themes. Examples of themes include Work, Family, and Education;
see Table 4 for a complete list. As we will show, these themes may
be discussed with different perspectives in different gendered
subreddits.

3.2    Commenting Similarity
We now identify other subreddits that users commenting on
r/Feminism, r/MensRights and r/TheRedPill are similar to in
terms of their interests. The intuition behind our method is as fol-
lows. If we find that, say, the users commenting on r/MensRights
and the users commenting on r/gardening also comment on the
same additional subreddits, then we would conclude that the
users of r/MensRights and r/gardening are similar [25].                   Figure 4: Subreddit user overlap matrix. Each cell is con-

   Furthermore, we convert the user overlap between each pair             3.3    Limitations and Assumptions
of subreddits into positive pointwise mutual information (PPMI),          There are several limitations of our methodology.
    (1) The iterative building of custom stop-lists for topic mod-
        elling and organizing topics into themes is subjective.
    (2) To decide whether a theme is popular within a subreddit,
        we only count the number of posts labelled as belonging to
        that theme. We do not consider the number of comments,
        views, upvotes or downvotes.
    (3) Our user analysis involves retrieving subreddits most simi-
        lar to gendered subreddits. Thus, our results only represent
        user interests on Reddit. We cannot capture user interests
        that are not explicitly represented as Reddit forums. For
        example, if the users of r/MensRights are interested in
        gardening, but there is no gardening subreddit, then we
        would not discover the interest of r/MensRights users in
        gardening.
Furthermore, we emphasize that we do not attempt to verify
                                                                                  Figure 5: Perspectives on Health / Abuse.
