Does KS law not already not allow all private biz's to deny service to any one for any reason? I ask because I see these often enough in KS and MO:
The Federal Civil Rights Act guarantees all people the right to "full and equal enjoyment of the goods, services, facilities, privileges, advantages, and accommodations of any place of public accommodation, without discrimination or segregation on the ground of race, color, religion, or national origin."
So you can't refuse service on the basis of any of those protected classes but you can based on anything else. Some states have laws that basically add sexual orientation and/or gender identity to that list. Kansas does not - so right now people could already refuse service if they want to based on sexual orientation.
