Telling people they have to sell their home to those they don't wish to.
In the US (I'm assuming you're that way inclined) there are some protected characteristics that you can't discriminate against, such as race, colour, religion, sex, nationality, disability, family status etc. Now, I'm assuming that "to those they don't wish to" is for reasons
other than they are being a bigot? E.g. you just don't like the person? They were rude to you? Then there is no law that prevents you from not selling to them, is there? If you think there is, perhaps you can provide detail?
Telling people they have to do business with those that they don't wish to.
Again, other than for reasons that you're bigotted, there are no laws that stop you doing business with anyone you don't want to. I.e. there are laws that prohibit your reason for not doing business for, as previously, race, colour, religion, nationality, sex etc.
Are you against these anti-discrimination laws, or are you suggesting that there are
other laws that prohibit you from refusing to do business with whomever you choose? If so, care to share which ones you are referring to?
In the US, if you open for business, you do take on legal duties, and one of those is not to be discriminatory. This is your duty if you wish to benefit from trading with the public. It's a trade-off, so to speak: you benefit from being able to trade with the public, so you are required not to be discriminatory. Are you against this trade-off?
Telling people they have to hire those they don't wish to.
Again, the only laws that might prevent you from doing so are the
anti-discrimination laws.
Other than these, there is nothing to stop you
not hiring someone. Noone is forcing you to hire
anyone.
But, if you do recruit, you can not discriminate against protected characteristics (sex, age, religion, colour, nationality, race, disability, etc). Assuming someone is able to do the job that you advertise for - with only minor accommodation for disability - then you can not discriminate against them. If you're not doing that, then there are no other laws that I'm aware of that mean you have to hire someone you don't wish to. Can you detail which law you're referring to?
It does seem with these three examples of yours that you have something against anti-discrimination laws, as these would be the only laws that would prevent you from doing what you are suggesting.
Is this the case, that you think people should be allowed to discriminate against race, against sex, against religion, etc?
