What exactly is elaborate about a plan to shoot people?

It isn't, but people accuse him of shooting people to scare away others which requires more thought. The murder is obviously premeditated, I am not arguing about that, I just argue that he probably didn't do it for any higher purpose than wanting them dead.

He shouted "Get out of my country!" I'm pretty confident that was not directed solely at the person he then shot.

So you argue that it wouldn't have been terrorism if he instead said "Death to all naggers!" because then it wouldn't serve a higher political purpose? To me those two statements are basically interchangeable in this scenario.

"Death to..." and "Get out of my country" don't seem very interchangeable to me.

Ok, better example: Imagine that he yelled "Get out of my lawn!", would that be obvious terrorism?

Only if they were part of a political movement whose platform included keeping people who look like that off lawns.

Are you saying you think he only wanted specifically those two men out of "his" country? I suppose it's possible but I wouldn't bet money on it.

Elaborate plans are not necessary. All you need to do is radicalize the right people, and plans (and actions) will take care of themselves.

You're right. He should have bragged about it on YouTube instead. Everyone knows that's where the real terrorists do their bragging.
