Religious Exemption Laws

As in these laws, I mean tax exemption, scumbag exemption and child abuse (I've heard cases where couple choose prayer over hospitals and their child dies, and they don't get charges pressed against them). After doing research, I saw that secular organizations aren't tax exempt and yet religious organizations are, what the fuck? And another reason why I think these should be abolished is because the first amendment explicitly says "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances." That's right there, in the first fucking Amendment, so these religious laws should be unconstitutional.

And besides, abolishing these religious exemption laws wouldn't hurt anybody, since the first amendment promotes religious freedom, however; I don't fucking see why people don't see "freedom from religion" as a right.
