Ditto here. I even wore a Darth Vader T-shirt back in the day.
I was also pro-Empire. They seemed not only powerful, but sensible. I can't stand people caught up in idealism, like Princess Leia.
You’re definitely not going to like the Rebels’ inspiration then: They were based on the Vietcong. Don’t believe me? Lucas makes it very plain and clear in these sources:

In fact, technically, by rooting for the Empire, you’re also showing your patriotism to America as a good thing, since the Empire according to Lucas was based on America during the Vietnam War.
