Reddit keeps deleting posts I make regarding certain topics

I've made in the past a post about:

1. In a ('badass history' sub? Can't recall the name but they always post about US military) I made a post about a Vietnamese soldier who conducted some really amazing attacks during the Vietnam war; this post was automatically not allowed.
2. In the leopards eating faces sub I made a post about Denmark now being invaded by America after helping us invade Iraq; this post was also automatically not allowed and the mods ignored my DMs.
3. This one right here in the too afraid to ask sub.

That's three subs that either seem to lean a certain way or perhaps automatically disallow posts by people subscribed to late stage capitalism (a thing many subs did to people subbed to the old CTH sub).
