I became an OT purist the day I saw ROTJ in the theater for the first time after seeing the other two. At that point I was like "the Star Wars Trilogy rocked". That was the "Trilogy" ..... that was IT. I was like 12 when that happened.
The SE came around years later and made me re-appreciate them even more though I will say that as a standalone anniversary presentation I was and still am cool with the 1997 SE.
That is all ...... :)
