In a gallon pouring pitcher, steep 8-10 family-size tea bags in boiling water. Stir in the sugar immediately, so it dissolves. Let the tea bags steep for about 20-25 minutes.
While the tea bags steep, soften the raspberries in a medium saucepan over medium heat with ¼ cup of water. Press the berries through a fine mesh strainer into a large Pyrex measuring cup. Discard the pulp and seeds.
Remove the tea bags. Add the berry juices into the tea. Stir. Add 2 cups cold water and plenty of ice to the pouring pitcher. Pour over ice and enjoy.
