I would not attend a gay wedding and care not at all what anyone chooses to think about it. I do care what God thinks about it, which is why I would not attend.
I did purchase a Bible online last year, so according to Jim Jordan, I am on the FBI’s watch list for being a domestic terrorist.
Not to worry about online only.
If you use electronic money (credit card - ApplePay - etc) the POS machine knows WHO you are, WHAT you bought, WHERE you bought it, WHEN you bought it, but not WHY you bought it.
If you used real money, then you can be placed in the store that sells subversive material by the CAMERAS that have watched you from dozens of locations as you entered the store.
If you posted online about your purchase - they know.
If you talked face-to-face with a friend and THEY post about your new purchase - then they know that, too.
Have a nice day! (and the same to you - NSA watchers...)
