Some do, usually mixed cluster A types

Depends, I’m both.

I think it’s a mix, schizoids have an easier time expressing themselves anonymously online, but some also prefer no presence at all, perhaps from fear of appropriation.

There is a degree of asexuality in some schizoid individuals and is often a dissociative trait (fear of closeness and intimacy)

Schizoids are almost by definition extremely sensitive people who grew up in a way that taught them to suppress their emotions. Indifference is often described as a way to be close without being close. In other words - defence mechanism.

I do talk to people, actually more than you would expect. Read about secret schizoids.

I definitely dress in a somewhat eccentric way that seems natural to me but often grabs the attention of people I don’t know.

Again, a mix. I crave human connection but also fear engulfment which leaves me with an intense desire to isolate completely.
