This argument is a slippery slope that doesn't have a good end. Using the same argument I could say you shouldn't treat anyone who's been in a car crash because it was God's will that it happened so they should just have to deal with it. Or you can't treat cancer or any illness because it was obviously God's will that they have it. No medicine can be used at any time . Oh and you can't use cars, planes, trains or boats since God didn't straight up give us those things either so how can they be God's will. You can see it's a stupid argument. You know what he did give us? A brain and the ability to invent things. As a being who knows everything pretty sure he knew exactly what we were going to invent. If it wasn't his will to invent something don't you think he could have done something to stop it? Think it's time to get off your high horse and face the fact that just because you don't like something doesn't automatically mean it's wrong.
You know what would have been a better argument? Saying I don't want my tax dollars paying for something that someone doesn't actually need to live. That's a valid opinion. While it's not really a "nice" opinion it is at least something that doesn't rely on a higher powers will that only you seem to be able to determine.
It's called satire, using an extreme argument to demonstrate the invalidity/inaccuracy of a related argument. Its not supposed to be reasonable or logical
It's actually pretty rare for doctors to prescribe sildenafil for blood pressure because most insurances don't pay for it and when they do write for it it's always the 20mg (Revatio) not the actual Viagra (50 or 100mg)
That's nice
