"Oh my god that religous guy is so dumb and brainwashed, he thinks the big bang isn't real"
How does it make a person dumb not to believe mainstream science? I bet the vast majority of the people who say they believe the big bang have only a vague understanding of what the big bang really is. Just lol if you think your average guy reads and understands scientific journals. If you believe the big bang, chances are you believe it because either a) your parents told you, b) your teachers told you, or c) the scientist on TV told you. It's the exactly the same as a preacher telling you the earth was created 6000 years ago.
This is why I cringe so much whenever I see pseudo-intellectuals bashing people for:
not believing the big bang
not believing evolution
being against having their children vaccinated
Mainstream science has been wrong in the past. 150 years ago mainstream science believed light travelled through a medium known as "Luminiferous Aether". Now mainstream science rejects the existence of luminiferous aether.
