Perhaps "how queer" was the intended use. Or, think Sherlock saying, "Hmph. Strange--Strange indeed!"

> Strange implies a negative value judgement

It sounds like you've internalized some negativity around being "not-normal" -- how I would define "strange".

In a society of vice, greed, and perfidy, acting nice for no reason is "strange".

So, as many things that can be compared and have a "normal" can be strange.

Deviant implies negativity, but I would say pacifists are "deviants".

Any negativity with "strange" has to come with context.
