The War on Religious Liberty

Senator Ted Cruz recently spoke of the Threat to Religious Liberty™.

Cruz said, ”As believers, we are called to action; not just sitting quietly and hiding our faith under a bushel but to stand and speak no matter what the consequence.  Religious liberty has never been more under attack.”

Exactly which liberties are being lost, I wonder? How many churches have been closed? How many Bible Burnings? Did I miss the invite to the burning? I got the one for the Quran Burning. But I didn't get the invite to the Bible burning. Has there been a slaughter of Christians in the US? I've been invited to the slaughter of all Muslims, but haven't heard about the Christian one. Has Senator Cruz been prevented to going to church? From praying? Sending his children to religious schools?

Or does he mean that his religious liberty is being  attacked because he wants to impose his religion on others?

Can someone from Senator Cruz' office post his reply in the comments?
