I can, as I am actually a Republican (and a conservative Christian one at that!). I should add that I don't watch Fox News though. That audience tends to be over the age of 50. People my age (40 and under) are the Dailywire, PragerU, Stephen Crowder types. It's a little different in terms of styles, with some difference of beliefs. Tucker Carlson and Ben Shapiro are likely the most overlap between those two groups.
Anyway, you are not too far off on what the thinking is. 1) Correct. 2) Correct. The belief was that there was no real proof that masks work. There's now proof that masks do not help those who wear them. There's the thought that masks might help keep others from getting infected, but this has not been proven. 3) More that people HAVE to go to work and keeping kids (who can get it but are not a meaningful transmission vector of the disease) from school has serious long term affects on them. Especially low income children, which is ironic since it's usually Democrats who claim the care of low income families. Super spreader events - you've got it mixed up. The annoyance from Republicans is that Democrats believe that some events are either not super spreader events or get to be exempted from shame. So you can have a BLM mass gathering, or you can celebrate Biden, and that's fine. But if you get together to protest the lockdowns, or support Trump, that's shamed via the media. 5) I'll add some. Lockdowns are a delay tactic and don't actually save lives. At best, they could keep hospitals from getting over run. Otherwise, the only difference between an area that got Covid and an area that locks down but eventually gets Covid is the added pain of the lockdown.
This added pain isn't just economic. It's suicides and drug overdoses and mental health. It's a high cost.
In general, the problems most Republicans have is the hypocrisy. Masks were originally ineffective, but now they are necessary. 15 weeks to slow the spread...or maybe a year. You can't get a haircut, or you need to cancel Thanksgiving, unless your a senator or a mayor and then the rules don't apply. We must follow the science, unless the science doesn't support our beliefs than it's bogus science (see the Danish mask study that was suppressed and even now is being ignored). There's also the problem that every decision on Covid seems to be to give government officials more power. We're in general not trustworthy of those things.
