if someone can make a valid and reasonably logical defense for something being here
I think this is key. Some films will be obviously gay-themed (by most definitions), while others will need an explanation–and that can add to the enjoyment of the film. If the "gay connection" is not obvious, and it's not explained, users should expect a gentle comment to the effect of, "Is there a gay theme here?" Responding with a hissy fit that one of the day players in scene 241 was gay in real life doesn't cut it...although we see that a lot.
Uploaders shouldn't think of their torrents as raw meat tossed into a shark tank, but rather as a menu item for viewers to consider. Make an argument why a person should invest not only dowload volume but the time to watch the film.
