A lawsuit in Seattle pits some fundamental rights against each other its civil rights that ban discrimination, and property rights that allow owners to decide what to do with their homes and land.
There is no fundamental civil right that bans discrimination.
Discrimination in government action is banned under the requirement for equal treatment under the law. Private parties should and do discriminate for a number of reasons all the time. Requiring non-discrimination of private parties destroys freedom of association and private property rights.
Shhhhh! Not so loud! People might start getting suspicious about the motives for this law.
Speaking of parties, by the same logic when you hold a party you should issue a public invitation and accept the first n people who RSVP.
