Anecdotally when I was young. I only ever found Homeschoolers weird. But that is specifically because the ones I knew personally fit the negative stereotypes to a T.

The rest I didn’t find particularly weird. I found two rather annoying and insufferable at a personal level rather then weird. Most of the listed groups kept to themselves and let you do your thing if you let them do theirs. Though the Conspiracy guys were more then willing to talk your ear off if given the chance.

But I did find organic food eaters and devout church goers I found insufferable and annoying. Rather then weird. As again at an anecdotal level. The ones I knew fit the negative stereotypes associated with them.

The organic guys never shut up about their diet and how healthy it was and how the rest of us plebs were killing our selves with processed junk.

And the devout church goers always judged you and thought themselves above you because they went to church constantly and observed every obscure Christian tradition and holiday. And probably unsurprisingly. Their kids were some of the most miserable people I knew. Only one maintains any sort of contact and relationship with his parents now.
