X person is still allowed to take idiotic bigoted stances, and to provide funding for harmful and antisocial causes...
Potential and former customers and business partners are free to use his objectionable speech -- and his objectionable spending on harmful causes -- as a reason for not patronizing his business locations or partnering with business ventures owned or operated by him.
The business owner is not legally obligated to be reasonable, and customers are not obligated to support him.
Also, I must remind folks that incorporation of a business is a privilege, not a right. Corporations -- through the charter process -- are *supposed* to be held to a standard of demonstrating and sustaining benefit to the communities in which they operate. In the absence or effective elimination of the charter revocation process, specific cities or communities reasserting their right to deny privileges to harmful organization seems a perfectly reasonable substitute. Corporations are legal fictions, not ACTUAL people (regardless of what certain atrocious legal doctrines may hold).
