Not sure where you get the idea, EXCEPT for the 9 black-robed tyrany, that our Rights are ‘not absolute’ (and they call us L’tarians kooky here)
BOTH are Rights and both in the 1st: of Religion and of Assembly (the latter being how one can ‘discriminate’ for OR against anyone/thing else).
If a biz owner wishes to discriminate, for WHATEVER reason they deem, it is THEIR biz to do so....I have as much a Right to NOT associate and/or shop there. *I*, nor the gov’t, pays for that biz employees, taxes, fees, utilities, etc.; nor should the same be making rules/etc. that might be counter to the biz/owner.
