More than messengers I see them as self appointed guardians of the environment. That is a noble task, and I applaud the intent.

To the extent that they are self appointed messengers of warning, my point is that they have worn out their audience with torrents of trivial messages. Therefore they failed in their mission and failed to communicate their message.

I'd like to shoot them for not having enough sense nor discernment to distinguish between serious and trivial. Also for not having enough communications sense to shut up once in awhile instead of becoming irrelevant white noise background.
