I'm sure it happens, because we are all humans, and humans can be irrational. But it's not the norm, and it's not something that lasts very long in science, as you said. That lies in stark contrast to religion, where irrational beliefs persist for centuries. So while I can't dispute the claim, I don't see that it really matters -- it's somewhat tautological that there would be some irrationality in a field as long and broad as science, but it is not representative of the field as a whole.
I've read his objections, and everything I've seen suggests that you have things backwards. He did not object to the Big Bang on the basis that because it resembled creation myths it had to be wrong. He objected to it because he considered it scientifically unsound
in the same manner as religious arguments are.
To wit:
Emphasis mine.
Provide some sources and I'll consider it.
Sorry, you're trying to shift the burden of proof here.
I fully accept that Hoyle
could have had personal bias. I just won't accept that he
did have personal bias on this issue until you provide some evidence to back up that claim.
