One thing that is often misunderstood is how much time editors have in a day to deal with your question or manuscript. Many of them (most of them) have full time jobs and are supporting the publication in their "spare time", or at the very least, juggling it with a million other activities. Be happy you received a response. Also, it appears the editor actually took the time to answer your specific question - maybe they copy/pasted into their form rejection.

It's never personal. And your question was answered. To pdichellis's comment above, there are several publications that accept reprints. Find those.

Good luck!
