Do you understand the concept of the deathtrap cover at all? That's what this is. And it is done to men as well as women. How many times have we seen Batman being lowered by chains towards a vat of some bubbling vile liquid? How many times have we seen Spider-Man on the ground broken-looking, costume torn up, with Venom or another villain looming over him poised to finish him off? Do I need to start finding and posting these things? How about the laser pointed at James Bond's crotch in Goldfinger? The ending of literally every other episode of the 60s Batman TV show? You're being obtuse if you don't recognize the technique being used here.
Beyond that, your objection seems to stem merely from the fact that they're pretty and designed to appeal based on their looks and their sexiness. For that one, I suggest you ask the Goddess. She made us to respond to attractive people, and enjoy sexy images. I've yet to understand why that's so wrong beyond a prudish anti-sex agenda that I cannot possibly agree with.
What really frustrates me, though, is how you keep bringing up hentai and using terms like "naughty tentacles". One more time, THERE IS NO SEXUAL THREAT. The alien in question is a FEMALE BROOD QUEEN, those tentacles are her ARMS. The threat to the team is DEATH, not sexual assault. The idea that this is a "rape cover" has been 100% thoroughly debunked, yet you keep referring to it to bolster your argument. And it's thoroughly disingenuous.
What you're doing is called a Straw Man argument. You build up something everyone can agree is wrong, in this case a depiction of tentacle rape, and tear it down instead of addressing what's really at issue. It's both a logical fallacy and a dishonest debating technique, and I wish you'd stop. Argue what's there, not what you add into it, please.
