Bad? Not necessarily.
Dangerous? Yes, emphatically YES.
Any mass of people who believe whole heartedly that they must not pursue evidence that disagrees with their belief is inherently dangerous.
It's called brainwashing, and it's never used to support a truth... truth does not require faith... nor can it co-exist.
All religions make one fatal mistake.
They provide a claim, and then seek evidence to support it.
None of them have ever found that evidence.
We however do not make claims, unless we encounter evidence which demands a claim be made for it.
It is in this process that we cannot be "wrong".
It is by this process that we know religions are wrong.
What is our evidence?
Our evidence is simple, and inescapable.
They have made claims for which they have been desperately trying to find evidence to support for thousands of years.
Our evidence is that they have none.
Our claim is that they have made an unsupported one.
Thousands of years to provide their evidence... quite frankly, time's up.
We however have entire libraries filled with evidence supporting our claims, from the structure of the atom, to molecular bonding, scores of results from physics tests, chemistry tests, museums filled with the evidence of evolution through not just thousands of years, but millions. We have shaped our entire world using what we have discovered. You need not look further than your microwave oven... your television set... just about everything in your home is due to our discoveries.
... and none of it agrees with the claims of religions.
Time's up religion. Best get off the tracks before the discovery train explores your faith in its brake line.
