What tea would you recommend to someone who completely hates tea?!

I would recommend making sure you are actually drinking tea :) Well, at least in my country a lot of teas sold in common shops and supermarkets are horrible cr*p which can't be called a tea. I recommend finding a place that really specializes in teas and then taste various types of teas. Usually such places offer you to buy a cup before or without buying the whole tea package. If you are not very knowledgeable about all this teas stuff, it would be rather hard for you to tell apart a normal tea shop from a fake one, I would recommend checking this site (it's not spam, that site is a rather well-known source) http://teaspring.com/
Just click through basic categories (Green, Oolong, Pu-erh, White, etc) and quickly look though them to gain a basic idea of the variety of teas. Then when you come to a shop that sells a generic Green and a Generic Black tea, that's a fake. When you come to a shop that sells all those varieties of teas and are educated in this matter which means that they can answer various picky questions: when and where this tea was gathered, how exactly they achieve the specific taste for that tea, how is this tea produced, why you use the water of this temperature when preparing this tea, etc., then that's a good place :)
Once you find such a place just pick a random teas from a random category and buy a cup. If you don't like it, that's fine, the teas are very very different and it's ok if you don't like some of them. In this case just come next day and pick another random tea from a different category. Also don't give up on the whole category if you didn't like a tea from it, the teas are very different even within a single category.
This way is also good because you won't need to look into how to prepare tea (various categories of teas need to be prepared in different ways, e.g. you will totally destroy white tea if you use hot water), the shop assistant will do this stuff for you.
Oh, by the way, never put sugar into these teas. Basically the general idea of putting sugar into tea originates from those horrible fake teas.

Good luck!

Oolong, Jasmine, green. Hot and without sweetener or cream. And in that order.

I also love Tamarind iced tea. For an upset stomach, try Chamomile tea. Tasty!

I think what most people dislike about tea is the fermented darkness of "orange pekoe and cut black teas," like those served in America, especially as iced tea. God-awful stuff. To choke it down it must be loaded with enough sugar to kill a six-year-old. Hence, what Southerners call "Sweet tea." That's hardly saying it!

And you should give Green Tea Ice Cream a try! It's surprisingly delicious.

Try Lipton's Iced Tea or any instantaneous lemon iced tea!! By far its the best tea I've ever tasted and I also do not like teas!! To make it even better if you like it to taste stronger, add a little more of iced tea powder in the mix and add one green lemon (yellow's fine also but add 2) slices to make it even better!

My mom!! Thats the reward she gives me for cutting the front lawn! And its nice..and Tangy..

Try some peach tea that's usually a sweet tea but if you like citrus maybe regular tea with some orange peel in it

my aunt loves tea

Try some fruity tastes, like strawberry, for example. It's awesome.

Tazo Passion tea

Chai Tea or Green Tea is pretty good.

find a good iced tea, like luzienne or liptons. those are pretty much standard iced teas.

I just got a new one... Chocolate Chai and it's SO yummy! put in a little sugar and milk and it's really tastey

Chinese green tea.
