To add to the "etc.", those under the voting age and immigrants.

I believe some religious groups don't vote. Ahh, yes, https://en.wikipedia.org/wiki/Religious_rejection_of_politic... gives examples of people involved in politics but don't vote for religious reasons.

Even if the complaint is specifically directed towards those who can vote, but don't - is Australia, where everyone is required to vote, free of "preachy posts"?

I suspect not.

Note also that what touched the nerve is a posting from someone who hasn't said if he is or is not voting, not that he hasn't voted before nor won't vote again.
