fat:
you cannot evangelize a niche fetish lol
Lol that's a good way to put it. There may be more folks into it here in the US but that doesn't mean the general population accepts it.
As far as trying to get a lot of people interested, good luck. Human nature means most people will attack anything they see as abnormal, even if it was considered normal a few years earlier.
About the only way you would make this fetish widely popular is if there was an easy way to make money from it and you appealed to people's greed.
