Sure it can. Someone may easily respond that the reason the service member was killed was because of a needless war or some such stuff. Not a stretch at all. Also - what may not look like political to you, may to others, and that can make them think its ok to go a little further. Then when their post is deleted, they point to the original service member post and say "how come this is ok but mine is not?" --- Its a tough position for us...
Besides all that - why is it such a big deal to post it in the political forum?
Again - why not avoid the whole thing and if its political or near political, just post in the politics forum.
