If it isn’t sweet to you, you’re making it wrong. As some of the other commenters have said, assuming you’re talking about Southern style sweet tea, the stuff uses so much sugar that it will not dissolve unless it’s added while the water is still hot, like 1 or 2 cups of sugar per gallon of tea was what my family used growing up, but some places will literally cram in double the sugar content of coca cola from what I’ve heard. Sweetener packets just ain’t gonna cut it.

That being said, while I grew up with and love the stuff (though try to drink it only occationally and make it with sucralose now, because it’s a truly ridiculous amount of sugar to consume as one’s main beverage), I think you’ll find your view less unpopular than you think, except among Americans (especially southerners). I remember being surprised to learn growing up from some foreign classmates that it’s considered something of an acquired taste, if you didn’t grow up with it, there’s a pretty decent chance you won’t like it, to my understanding.
