Chik-fil-A does not discriminate in who they hire or who they sell franchises to or who they serve. They have a corporate model that is wonderful and they try to set an example but they are not going to start to actively discriminate because that would be the beginning of the end of their restaurants.
Chik fil A absolutely "discriminates" in who they sell franchises to. You obviously have no idea what they do in that regard.
To be "awarded" a Chik fil A franchise, one must be a Christian, preferably married with children, an active participant in one's home church and a whole lot of other requirements.
To be awarded a Chik fil A franchise, the applicant must undergo a year long process under direct supervision of a Chik fil A Senior Manager, the applicant's family life is scrutinized, so are their finances and a whole lot more.
Chik fil A franchises cost a whopping $5,000 and there are over 25,000 applicants for franchises each year for somewhere around 15-20 new restaurants each year.
You cannot say Chik fil A doesn't "discriminate" in who they award franchises to, they absolutely do and that's their right.
