Eh, no. This isn't about not accepting scientific output under a Republican president – science was well received under Bush, as I recall, and will continue to be under Trump.
This is about the fear of losing scientific data that has already been produced.
But the subtext is that any 'discoveries' or 'corrections' will be rejected out of hand.
The prime ones being the recent corrections to the land temperature record that cooled the 1930s and 1940s and heated 2009 onwards yielding a steady linear increase graphic.
When those corrections are placed under the microscope and likely reversed, what will the reaction be ? Scientific shills of the Republicans are making up Alternative Facts... here is our precious archived dataset that true believers can reference.
No, this is complete FUD, and disingenuous at best. What people who care are worried about is a repeat of what happened in Canada under the Harper government where the data was simply not available at all.
[edit] the difference is that it's not the administration or even the EPA that is putting it's reputation on the line if the data was manipulated, but the individual scientists themselves. No one with any sense believes that a scientist is going to fall on their sword and ruin their career just to make up some BS talking point that Trump can run with.
