That's exactly how I'd write it, save for the em dash with spaces around it, which is not how em dashes are normally used in English language.

I think it's an overreaction.

What? That's exactly how em dashes are used in normal English.

An em dash is used without spaces in most typography manuals. But that’s for typeset books, it’s not like everybody writes that way in casual communication.

I think surrounding it with spaces comes from people using a regular dash (the em dash is not readily accessible on the keyboard), then surrounding it with spaces to make sure it’s not interpreted as a dash.

I use (or used to) mdash with spaces, I've always just found the mdash when it collides with the words to be ugly.

I've read a few typography related books and checked some style manuals in my time, but no-one has ever 'corrected' my usage so I think it's alright.

I was listening to a podcast recently that had interesting information about the birth of mdash - "99% Invisible: The Em Dash".
