Now that the pentacle has been approved to be placed on Veteran memorials, do you feel that other symbols of different pagan faiths (the druid sigil, thor’s hammer, etc) are as equally important to fight for?

 If it's important to you, go ahead. I think that any symbol a person feels is important to them should have place on Veteran memorials, or any headstone for that matter. I don't think they should limit it.
I'm not really familiar with the Australian military memorials, but from what I've seen (which is limited to two memorials I've been too), it's entirely non-religious anyway. I'm not connected to the military, so it's not a personal issue for me. As far as I know, I could have "Go fuck yourself" etched into my tomb stone when I die, as long as I pay for it to be written, same goes for symbols. The more words, the more details, the more money it costs.

I think it should be open to the individual to decide exactly what they want, regardless of whether it's military or not.
