I agree.  East Lansing is wrong unless he refuses to sell apples to all comers, including gay couples, in the market under their control.  If he rents out his farm for other weddings, that is another matter, but it has nothing to do with the City. Nonetheless, it is a Civil Rights Act violation under the heading of public accommodations.  If he can't be a gracious host, he needs to get out of the wedding business and examine whether his feelings about these weddings are moral or tribal.  Don't confuse the latter with either spirituality or liberty.
