Basically any activity that doesn't involve public accommodation. Churches, scouting, country clubs, social clubs, etc. can and should be able to discriminate based on any reason or no reason. Hotels, restaurants, libraries, public pools, etc. shouldn't.
Scouting has been under serious attack for over a decade for not allowing gay scoutmasters.
Hotels, restaurants, libraries, public pools, etc. shouldn’t.

How about public schools? By your logic they should be required to allow homosexual clubs and activities even if the school board and voters are against it.
I hear you with hotels and trains (personally, I think capitalism does a fine job of getting rid of that sort of discrimination now that jim crow is gone . . . money is money). The problem comes when that legal precedent is applied to gay clubs in school while excluding Christian ones, requiring sex education that is on equal terms for heterosexual and homosexual sex, speech codes that make stating Christian beliefs an offense . . . it all ties together. I do not think the anti-discrimination laws are needed anymore and are doing more harm than good. Yet they are expanding (as all law and bureaucracy does).
Jim Crow is gone . . . laws getting rid of Jim Crow should be gone too.
