It used to be considered to be pretty bad form to go cross forum like this.
However, it's really not worth worrying about, I'll bet John Bailey isn't losing any sleep. There's barely a "name" angler out there that won't have a collection of detractors. Whether or not they actually deserve to have detractors is another matter entirely.
I actively try to avoid it, but have had the odd minor brush with some "names". I've met some distinctly average anglers that are lauded. Some are guides, some angling authors/journalists. Some are rather economical with the truth along the way. Some are downright thugs, liars and backstabbers. It shouldn't come as a big surprise when others are only too pleased to shoot them down. Even if they don't deserve it, good old jealousy can be enough of a motivation for some.
Personally, I can't think of anything worse than being involved in all of that nonsense. Just take it all with a pinch of salt. However, be wary of putting anyone on a pedestal. Things are not always as they appear.
