What happened to topics related to military ie legit questions, advice, information and good discussion?

They are still here and there are usually a few dozen posts that go up on a daily basis.

At the top left of your page, click on "home" and then "answers" (i.e., https://www.rallypoint.com/answers) - those are the ones that the admins do strict moderation on to ensure they are appropriate discussions.

As to the mudslinging the left and the right do - that's limited to the "Political Opinions" topic. As long as the users don't violate the terms of service or standards of conduct, they are free to post on all manner of topics.

Ive recently returned to this social site after a significant break, just to find it to be headed the same way MySpace did. Even the app for this place is not retrievable from Google Play. Something glitch great potential was either mismanaged or was outcompeted by other social media sites. It's kind of sad, really.
