Why should those rights supersede others rights to life?
Mainly because the premise that allowing people to exercise their explicitly-asserted First Amendment rights violates anyone else's right to life is a flat-out lie, and those of you telling it know damn well that you are lying.
Nope, it's not a lie. Congregating in large numbers increasing the spread of COVID-19. Not just among church-goers, but among those with whom they come in contact. That selfishly puts others lives in peril and unfortunately for some, brutally strips away their right to life.
Your pathetically weak excuse fails to justify placing the right to assemble above the right to life.
That is the legal/constitutional justification. There's no social need to ban snake handling, or even peyote use, if it's central to the exercise of religion, because no one besides the faithful are impacted. But the virus WILL WITHOUT ANY QUESTION spread outside of just the people assembling in some religious setting, because the faithful will not remain quarantined inside the locale of the religious setting.
So, if someone want to assert the regulation goes too far in banning the assembly altogether, they have to address how the exponential rise in sick people is not affected.
