Honestly, if you're talking about covid, it's because "dissenting" science is hijacked by dumb science, and lumped together.

The "probably an unintentional lab break initially unnoticed then covered up" got lumped with the "aaaaah! China virus! Bill gates bad!".

Not by one person, in one comment, it's like a chain. Someone make a reasonable, skeptic comment, someone agree but goes further, the third one goes even further, and by the fourth we have a dumb idea that doesn't have any basis, and it's easier to reject the thread entirely.

But i made several comments highly suspicious of the real efficacy of mRNA comapred to usual deactivated virus (i do have a friend working at Valneva, so i might have been partisan), and had pleasants conversations about it, and learned a lot. But several time some big "vaccine = autism" guy showed up on the thread. It's just tiring.
