The Boy Scouts are a private club and have a right to determine membership. They are not offering something for sale to the public, or determining that they can only offer a product or service to select members of the public, they are a club for private association.
So would it be OK under your philosophy for the train company to make Frederick Douglass ride in the baggage car rather than forcing the people in the whites only train cars to associated with him?
Now there are really two different issues here.
A) It is good for the company to do such a thing, and would I offer them my business if they did so- no.
B) Do I think it should be within their legal rights to do so- yes. It’s their business, their property and hence I believe it should be their decision.
Don’t confuse my personal philosophy of right and wrong with what I think the government should be playing with.
If the rail line declares themselves to be a ‘private rail line’ then how are they any different from the Boy Scouts? The Boy Scouts will take anyone who wants to join (within reason). A business is no more or less of a private association.
Or should I ask, so you assume companies don’t have rights? Does the freedom of association dissolve in the case of a corporation?
OK, since we’re in the realm of companies offering services to the public and what they are allowed to do. Say I’m Catholic and I own an event hall. Do I have to host a gay wedding reception against my will?
