The point, that you missed, is that businesses can't dictate anything.
yOU'RE RIGHT THEY CAN'T AND CANNOT REFUSE SERVICE WITH OR WITHOUT A MASK
And you can't read. I didn't say they couldn't refuse service. I said they couldn't dictate anything.
they are dictating the wearing of masks
No, they aren't. They're saying, "if you don't wear a mask, you're not welcome hear. We won't serve you". The fact that you can't recognize that distinction is exactly why liberty is in such jeopardy.
that's a mandate on them of a medical procedure within their store
Nope. It's simply saying - 'This is my property. If you don't wear a mask, I will ask you to leave. And if you don't leave, I'll call the police to have you escorted out'.
Do you really think they shouldn't have that right?
Someone refusing to accommodate you isn't dictating to you. They aren't violating your rights. They're just refusing to accommodate you.
