Tracking religion is not so much evil as stupid, unless they push religion into a compulsory family generational requirement. You can not be any other religion other than the one you were born into by your parents, this as a legal requirement. Without this of course, with freedom of religion, you can change your religion from moment to moment, even quite legally make up a new one for any reason. The whole messy business of once you are tagged with a religion for what ever reason, parents forcing it on you, other individuals claiming you are or random reason what so ever, once tagged you are branded for life.
Sure you can control the literature, if religious works promote criminal activity, they should be banned or at the very least be made illegal to distribute to minors. Tough it causes at least three existing major religious works to be controlled until they are fixed in line with current laws, there is no excuse for their content, they could have been fixed decades even centuries ago but their crazed adherents refuse to adhere to modern laws, preferring barbarous primitivism and the dominate and control of sexuality, forcing themselves on others under the guise of religion. Religious work that promote criminal activity should not be allowed to be distributed to minors nor taught or approved of in any schools for minors.
