Because both liberals and conservatives seem to be having trouble understanding this lately, let's spell it out:
You are free to express any opinion you wish.
Your opponents, even the vilest, are free to do the same.
The fact that people may vehemently disagree with your speech and consider you [an immoral hell-bound God-mocker][a hate-mongering narrow-minded bigot] as a result is not "persecution".
The fact that your free speech may have consequences--for example, in influencing people to frequent or avoid your business, or inciting lawsuits for libel or slander or discrimination--is not "persecution" either.
Your opinion is not the law of the land, no matter how emphatically you express it.
