Well you could define what you mean by "not allowed to speak", and list the names of more scientists who you claim were bullied and "not allowed to speak". Science is evidence based: give us some evidence.

Or are you refusing to define your terms and provide any evidence, because you claim without any evidence that these theoretical silent scientists actually exist, but cannot be measured or counted, like undetectable dark matter in white lab coats?

That's not very scientific of you. (Or of Judith Curry, whose words you claim to quote. If she really promotes unscientific "silent scientist" conspiracy theories like that, then no wonder her colleagues are so critical of her! Calling bullshit isn't censorship, and she's anything but silent herself. So please link to your source where Judith Curry actually said those words that you quote.)

As un-silent, outspoken, widely published and nationally televised as Judith Curry is, she's said "I don’t feel like my professional status is being jeopardized or challenged or whatever" [1]. So Judith Curry's case is actually evidence that dissenting scientists (and even ones who "literally say" ridiculous things like you quoted her saying) are NOT bullied into silence.

"Judith A. Curry is chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology. She runs a climate blog and has been invited by Republicans on several occasions to testify at climate hearings about uncertainties in climate understanding and predictions. Climate scientists criticize her uncertainty-focused climate outreach communication for containing elementary mistakes and inflammatory assertions unsupported by evidence. Curry is a regular at Anthony Watts' denier blog, as well as Steve McIntyre's Climate Audit, another denier site. She has further embarrassed herself (and her university) by using refuted denier talking points and defending the Wegman Report, eventually admitting she hadn't even read it in the first place." [2]

"Curry receives ongoing funding from the fossil fuel industry. In an interview with Curry for a October 2010 Scientific American profile, Michael Lemonick reports (pers. comm.) that he asked Curry about potential conflicts of interest, and she responded,

"I do receive some funding from the fossil fuel industry. My company...does hurricane forecasting...for an oil company, since 2007. During this period I have been both a strong advocate for the IPCC, and more recently a critic of the IPCC, there is no correlation of this funding with my public statements."

"Criticisms of outreach communication:
Laundry list:
Curry's contrarian-leaning "public outreach" public communication is criticized by prominent climate scientists and other science-aligned climate bloggers for a propensity toward "inflammatory language and over-the-top accusations ...with the...absence of any concrete evidence and [with] errors in matters of simple fact.".

"...Examples of the unreliability of Curry's blog publications are illustrated by Michael Tobis and James Annan, who both showed basic flaws in her understanding of uncertainty and probability, or at least an irresponsible level of sloppiness in expressing herself. Arthur Smith pointed out an under-grad level misunderstanding in her own field's basic terminology," said Coby Beck.
Climate scientist James Annan has provided examples (with rebuttals) of assertions made by Curry on topics like no-feedback climate sensitivity, aerosols, climate change detection&attribution, and the IPCC tolerance of challengers; he finds there's a pattern of "throwing up vague or demonstrably wrong claims, then running away when shown to be wrong",

"Willingness to criticize based on second-hand info from contrarian, inexpert sources:
"In a 2010 comment she called blogger Deep Climate's detailed and well-documented investigation into the Wegman Report "one of the most reprehensible attacks on a reputable scientist that I have seen" even as she revealed in her incorrect synopsis of the charges that she had not even read it for herself. ... [i.e.] she shows herself ready to publicly criticise someone else in the strongest terms based entirely on second hand information gleaned from places like Climate Audit and Watts Up With That."

"Offering off-the-cuff, uninformed criticism of mainstream climate science:
Gavin Schmidt has criticised Curry for "not knowing enough about what she has chosen to talk about, for not thinking clearly about the claims she has made with respect to the IPCC, and for flinging serious accusations at other scientists without just cause.". (It goes on and on... see [2].)

"We've seen a lot of strawmen from Judy lately," [Stanford University's Stephen H.] Schneider [3] said. "It is frankly shocking to see such a good scientist take that kind of a turn to sloppy thinking. I have no explanation for it." [1]

So do you have any examples better than Judith Curry?
