So I'm curious as to how far you would carry this? Do you have the right to carry your weapon into someone's house? Obviously I would disagree. Very few of your constitutional rights past my doorway. Your 1st Amendment rights are certainly gone, as I'll damned sure show you the door if what you're saying, wearing, or doing offends me.
First Amendment: 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.
So if I am past your doorway Congress can make law in regard to all that, at least as applicable to me?
Or do you mean I lose my freedom of speech and can't say “No” if you ask for sex or shout for help if you otherwise assault me?
If I'm in your house do I have to convert to your religion?
I don't see why this is so difficult for you. We're talking BUSINESS property, not somebody's home. The cases are completely different. The rights exercisable by/on business properties are less than for "real" private property (i.e. the "castle" in "a man's home is his castle"). During the integration/desegregation/civil rights timeframe, the courts decided that business owners had no right to exclude blacks from their BUSINESS properties.
