My point is that we can maintain the expectiatoin that all religious and irreligious people should abide by humane standards and treat each other respectfully in the public spheres -- while acknowledging, at the same time, that people often face prejudice, bigotry, and discrimination based on their religious affiliation (or lack thereof).

Two things can be true, at the same time. The nuances of what exactly constitutes "religious liberty," as you've pointed out, certainly need to be debated so no one takes advantage of such a status. But religionism is very real, and any of our hostilities toward specific religious denominations doesn't erase that.
