There's no mention of gays, homosexuals, LGBT or any such thing in the bill.
Here's the actual bill: http://billstatus.ls.state.ms.us/documents/2016/html/HB/1500-1599/HB1523PS.htm
...except that the entire bill is related only to the definition of marriage and is clearly aimed at LGBT claims, and not to general religious accommodations as I outlined above.
