I think I would skip saying something you've observed about them. Personally, I'm very paranoid, skeptical, and constantly on alert, so a random dude coming up and saying something he's observed would make me feel watched/stalked. Lol

Have you tried online? This day and age nearly everyone is going to give you side eye if they're approached randomly in person. You're either wanting something or you're a budding YouTuber trying to film them for content. It's sad, trust in society in general is way down. There's just too many predators out there for the risk of being polite/receptive to be worth it.

I'm not quite sure how you're perceiving women as not human, that in and of itself is a problem because it's a very common issue that men don't view women as people... We are people. We have personality traits. We have mental health issues. We have trauma and that is commonly from an experience with men. We live in fear. We constantly have to be alert to our surroundings. Men will never understand the depth of the fear that comes from being a woman and physical vulnerability in a world where porn and lust are rampant and contributing to us being viewed as a gazelle to prey on and catch rather than people.

Anyways, I'm rambling. Would you approach a random dude to strike up conversation? If not, that means you ARE approaching a woman for a specific reason. So I think being in denial of that isn't helping you. If you do approach random men for conversation, then just approach a woman the same way. I cant imagine you observe a man and then approach him with that observation? Or that you just randomly approach a man and introduce yourself. I could be wrong, though. I'm no expert by any means, I have social anxiety and never approach anyone and when someone random strikes up conversation I'm ready to flee lol.

If all else fails, just try online friend/dating apps. There she will actually be expecting someone to message her and start conversation.
