Honestly, in the least combative & confrontational possible, your thoughts there are just an excuse to not reach out and engage with the rest of your world. It's a little sad (not you, the situation itself) because if more people had that same thought, it becomes a self-fulfilling prophecy with no one talking to each other and those people you allude to being an afraid to talk too for whatever reason become the only people out there talking. We're certainly not there yet and I hope we never get there
When I dye my hair all kinds of colors, random people talk to me (and the specific colors even dictate who talks). When I dress up in a suit, people treat me more seriously. When I dress like a contractor and drive my truck, regular dudes talk to me at gas stations. And when I dress queer, women (and some dudes) smile at me.
I'm not even outgoing personality-wise, which would help more. Personality's the mental equivalent of physical appearance. Think of it like acting: actors pretend to be a certain way, and if it feels genuine, it makes us love or hate them, intrigued or bored. It's a lot more work than changing clothes, but it works no matter what you wear.
That's why I gotta pick my venues. But those venues are shrinking and growing farther apart.
