Scientific theories become mainstream if there is a preponderance of credible scientific evidence that intelligent people can critically review and agree that said theory makes much more sense than competing theories with less credible evidence.
This isn't always true. I gave many examples before of mainstream theories which were later proven completely false. There is no reason to believe this couldn't happen again with more recent mainstream theories.
Now, one can take the point of view that MAYBE there is a possibility that a non-mainstream theory, such as a young earth theory, could in fact be correct, despite all the evidence against it. And that's fine. But to say that a young earth theory is "equally likely" as an old earth theory, is silly. To argue that shows a questionable ability to understand evidence and a dubious ability to think critically.
Anyone is free to think anything they wish.
Not agreeing with the mainstream doesn't mean they are wrong.
Not agreeing with the mainstream doesn't mean they can't think critically - in fact, in many cases, it shows they are thinking MORE critically than many of those who blindly agree with the mainstream.
Launching personal attacks on those who disagree with you or your mainstream ideas is completely ignorant, not to mention disrespectful to the rights of others to have their own opinion.
You can disagree, but to call anyone names or say they don't understand evidence and can't think critically is bulls***.
If you disagree with me, fine, I don't care. But I guarantee you I've thought more critically about this than you ever have and still believe as I do, and if you don't like it, go **** yourself because I'm sick of your BS bullying tactics.
