Because unless a party at someones house,a business provides goods and services to the public and is subject to the public's approval to operate. Forexample, a restaurant needs to meet public health standards but a private party's kitchen doesn't. You can discriminate based on age and race who enters yout private party but you can't refuse business based on that criteria if you offer services to the public. If you think that's crazy then you'd be stoked to hear I think moderation in for profit sites that ban user generated content (twitter,reddit,news comments,youtube,facebook,etc...) Should also be subject to similar requirements. Your ability to profit from doing business with the public is a privilege not a right. Your ability to peacefully assemble in private with no economic profit or with profit between prople you have an exisiting well established relationship with (without a public place of business or advertisent) is private activity and should not be subject to public approval.
