well i haven't played any assassin's creed games but yes they are gay , also the main reason i found from the thread you mentioned was that there are a dozen of different tags for gay games , not just the lgbt tag.
Viewing post in why is this website so gay ?
sorry dude but there are games which can be said that they are gay (not specifically gay focused) games.
