How do you deal with a religious family?

[Aractus]

As far as science is concerned there are an unlimited number of valid theories.

And only one way to become a valid theory - get evidence.

No, that's how to "prove" a theory.

Not if the simple ones don't have any evidence for them.

Again, you're incorrect. An example is the Darwinism theory that evolution is driven by DNA mutations - there are competing theories to this, and when that theory was first invented it had no direct solid evidence whatsoever for it. If it gets disproved it will still be a valid theory, just one that has been disproved.

The ability to develop theories involving the use of little direct evidence is a very important skill. So I completely disagree with you trying to say that they're "hypothesises", the term is synonymous with theory but the meaning is slightly different. In any case, there is valid evidence for the theory that Jesus is resurrected. It's only the quality of said valid evidence that is disputable, not its existence in the first place.

Those theories are more than just guess-work - as you seem to suggest. They have a lot of other evidence going for them.

But not direct evidence, that's my point. They're using I guess you could say rules about what they've learned and theorised about other things to apply it to new situations and develop theoretical proposals for where humans might have been at a certain time.

They should think for themselves, they can have their own ideas, they can make up their own hypothesis - but they can't make up their own facts and they can't make up evidence. Which is why they can't make up their own theories.

No one's making up evidence, no one's making up facts.

How exactly is this relevant to minority rights?

It's perfectly relevant. 1. if those groups had not been treated as being valid minority groups then solutions to the issue would never have been developed and enacted on - case in point the USA did not have anywhere near the success of containing the HIV outbreak as we did in the late 80's, but they had exactly the same opportunity. 2. It's a very clear example of acknowledgement of those groups and their ability to tackle such an important health issue when given the ability/support to do so.
