photograph and ID the homosexuals who participate.
Put their pictures up on a site akin to a “john’s site” where they can be publicly outed.
This way if any are working in any capacity for the media, they can be exposed as a reason for the pro-homo-bias.
I’m pretty sure there will be a lot of aggressive (which is not to say violent) picture-taking on both sides. Today’s protesters will post their pictures of the “homophobes” and try to ruin their lives. (YOUR example, on the other hand, is just about policing the media for bias.)
