Feet licking and toe sucking

Good afternoon community
I brought this up before and wanted to touch up on it again, so tell me why some people are really against toe sucking or anything to do with feet. They’ll say eww you’re a freak or nasty for putting feet in your mouth and stuff like that, BUT they will stick their mouth and tongue in an asshole and lick that, I would never chow on a asshole you can catch all kinds of gross stuff from there
There isn’t anything you can catch from a foot Mabe a little dirt or something like that. But why are the feet people consider gross for liking to suck a toe every now and then but as long as the feet are groomed their ok. But an asshole you shit from it every day even if you wipe there are still particles there.
