Who are these "many who want to attack that foundation"?

<<Catholics and Christians are losing the rights to practice their religion.>>

How about citing an example.

<<the Gvt. should not be forcing anyone to bake cakes, or penalize anyone who upholds their religious moral values.>>

The government doesn't force anyone to bake cakes.

The government doesn't penalize anyone who upholds their religious moral values (by which you mean, "Christian" moral values, of course). However, state employees must abide by state regulations, and businesses must observe civil rights protections.
