Next thing you'll be criticising laws against employer discrimination. If someone wants an all white company, what's wrong with that? You want to force employers to hire people they don't want?
Not sure if your analogy is correct. If someone wants an all white company is discrimination. But if someone wants swedish speaking people and they all happen to be white it's no longer a problem.
Same with the tenants. I might prefer to rent my property to a woman because she takes care of the place better and is less likely to throw a party. Is that a discrimination?
Point is if there's an objective reason behind it then it's hard to consider it discrimination, even if it segments the groups on race/gender/religion.
Actually in the states that can still be discrimination and you can still be charged. Obviously it would be judged by a jury of your peers, however people have been successfully charged with discrimination in the states even when they defended themselves with your exact argument. Ethical concerns aside your advice is extremely legally dangerous.
