If the answer is going to be "STOP LISTENING DON'T LET THE DOOR HIT YOU BYE!" every time someone poses a problem they have with the show - why have this forum?
For those of us who appreciate the way the show is structured and appreciate what our hosts are attempting to accomplish, especially compared to most shows in this genre which offer little to no scrutiny of credulous claims. Unfortunately there is a lot of charlatanism associated with the subject. The motto of this choice is 'to separate signal from noise.'
Ms. Talbot, with respect to her friendship with Robbert, is providing noise. She seems a credulous person who has become enamored with a person who is widely regarded in his own country as a fraud. (Thank you to the Dutch members who have been able to help us out here with translations and pointed out some of the other contradictions.)
But when Ms. Talbot, who admittedly has no technical knowledge and has said so, proceeds to argue with David on his interpetration of 'orbs' as dust particles, I don't blame David a bit for suggesting she is insane (though he didn't actually say that.) That's like someone who does not know Arabic arguing about a translation with someone who is fluent in the language. On what basis can you make such a claim. The last half of the show was a train wreck, provided entirely courtesy of Ms. Talbot.
What is suspicious here is people such as yourself who suddenly appear, have never participated before, and immediately take on the hosts of the show with your criticisms. This smacks of prior involvement with the guest. It seems like you have been sent at the behest of someone else. Given that you are not the only one who 'suddenly appeared' my guess is that you are here as the result of a 'rally' somewhere else where it was brought to your attention that the Paracast was attacking your favorite cult, so you are here as a vanguard of sorts to protect the honor and all that. We saw a lot of that during the last US election where one forum would rally around their guy and say, 'Go over to so-and-so's blog and defend against this slander!' Given the timing, it's likely.
Of course, I can't prove that because you are not using your real name and are hiding behind anonymity. You've also not established your own credibility. You've never contributed here and you seem to be a single-issue poster. You're not here to contribute. You're not here to learn, nor to provide information to others. That's suspicious.
So back to your question of why have this forum. It is so those of us who appreciate the approach can discuss the issues. Compared to a lot of shows, this is a breath of fresh air. If you're not comfortable here, too bad. You're entitled to find a place where you are comfortable, but the rest of us are not required to provide it.
