This post is aimed mainly at Americans.
Religious persecution has two sides: the persecuted, and the persecutor.
You are the persecuted if you are being hassled for, or prevented from, practicing your faith. You are the persecuted if you have no faith but are being hassled for that, or if you are being otherwise forced to fall into line with another faith.
You are the persecutor if you hassle other people for, or prevent them from, practicing their faith. You are the persecutor if you demand that other people abide by the rules or Scriptural interpretation of your faith. You are the persecutor if you institute, promote, or condone rules or laws that would cause people to lose their employment or suffer other harm or discrimination for not abiding by your faith.
You are the persecutor if you use your faith to justify preventing other people from living their lives as they see fit to live them, particularly if doing so has no impact whatsoever upon you. ("If that's condoned my kids might do it" is not a valid argument.) If what someone else is doing or not doing just "bothers" you, that's not persecution. You have control over your own mind. Don't think about whatever that person is doing or not doing. If you're obsessing about someone else's life, you have too much time on your hands. Get a hobby or perhaps therapy.
You are NOT the persecuted if your faith requires you to persecute other people, for any reason. In that case, you are the persecutor.
If you are a religious persecutor you might want to reflect upon what you're doing and saying to others. You might want to understand that the United States of America was founded with the intention and promise that religious persecution would not exist within its borders at all. If you're having trouble with that concept, please review the First Amendment to the U.S. Constitution.
If you're a "states' rights" person and you don't think religious freedom is meant for your state you should read your own state's Constitution because the subject of religious freedom is included in that document, probably somewhere near the very beginning. (Look for Bill of Rights or a similar term.)
[Edit: If your state's Constitution seems to contradict itself on this issue then refer to Torcaso v. Watkins, which settled such contractions in 1961.]*
If you can't understand the concept of religious freedom for every American, and if you can't bear to practice your faith while leaving others to practice their faith (or to not practice a faith at all, if that's what they choose), then you might want to find another country where you can persecute all you want. Might I suggest one of several countries in the Middle East or Africa?
My dad often said, "America: Love it or leave it." If you're a religious persecutor and you can't love the USA as it actually exists and was meant to be, then leave the country. Soon. Now. You're not a real American, and you don't belong in the USA.
By the way, this applies to ALL faiths. Christianity may still be the dominant faith in the USA, but it's not the only one or the most important one. There is no "most important" faith in the USA. Figure that out, and don't be a persecutor, or leave. The rest of us, who understand the concept of religious freedom, really don't want or need you here.
