They are all subject to individual interpretation. Socially constructed labels. One person's "weird" is another's "normal". Besides, no matter how many people you meet youll never know enough of the global population to be able to label the whole in any way shape or form.

Race is a social construct and the scientist still can't fit every human into any one particular racial group. Humans are too dynamic, by nature.

Yes

Yes yes and yes

I'm so straight I'm a weirdo
