Religious Liberty?

[Joods]

To what extant should religious liberty in this nation be respected?

There is separation of church and state for a reason.
The law respects your right to choose whom to worship or not worship.
The law respects your right to pray where and when you want to.
What the law is clear about is that you do not have the right to impose your religion on others or force them to worship the same god that you do.
You do not have the right to force others to pray if they don't want to.

I respect religious liberties. I do not, however, respect the fact that many religious people seem to think that this means they get to enforce their religion on others, without consent. That is when I lose any respect I had for the person and their views about religion. If you want to pray before your son's football game, go right ahead. But don't expect my son to be forced to join your circle of prayer if he is uncomfortable with it. And if you're the coach and you do this and I see that you treat my son differently (penalize him in some way) because he refuses to pray with you, we're gonna have a problem.

But.. at what point should the law respect religious beliefs?

Being as the law is an inanimate object, it can't really respect anything. But, read the US Constitution. 

When should allowances be made?

What sort of allowances are you referring to?

Surely companies, with a Christian basis should not be forced to provide contraception?

Companies with more than a certain number of employees are required by law to provide healthcare coverage. Period. If they are not paying 100% for that coverage and the employee has to pay for any part of that, then a company shouldn't get to decide on what gets covered and what doesn't.

A Christina bakery.. shouldn't be...forced..to bake a cake for a gay couples wedding?

No one is stopping any bakery from refusing to provide goods and services to anyone. A business isn't forced to do anything they don't wish to do. However, if said business enters into a contract with a person or a couple, then decides to change their minds about honoring that contract, they're going to have a problem. As long as they have not entered into any contractual obligations with any person or entity, they are not bound by law to provide goods and services to said individual(s).
