It’s certainly possible that in different parts of the world feet has differing popularities, but I know that in a lot of the parts of the US (and europe, and asia for that matter) feet is enjoyed.
I'm sorry, but your claims are not even remotely true. Instead of speaking randomly without presenting any reinforcements for the claims, I'm going to start off with a
413-response survey done on r/Cubers (Reddit is dominated by the U.S., for one). For the question regarding which events should be removed, the only triple-digit votes were casted for Clock (at 150) and Feet (at 148). Right off the bat, it is already an extremely unpopular event.
Additionally, the WCA itself claimed that the event was the least popular by a significant margin in their most recent post on the WCA homepage, just in case the 400+ survey wasn't enough.
Speak for yourself, but there is no real reason to remove it, and I will stand by that claim.
You clearly haven't read anything in this thread. Let's go over the reasons again.
1) Hygienic reasons: Feet is the only event that requires the use of a body part different to the hand (unless you write in pencil with your feet for FMC...), and in comparison, the foot is always in a closed environment beneath socks and a shoe, while the hands are out in the open and are frequently washed. There is a reason why "smelly feet" is a significantly more common phrase than "smelly hands". That being said, when it comes to the actual solving there are many issues right off the bat. From an aesthetic stance, there is already a noticeable stench filling the room as competitors remove their shoes and begin touching the cube with their feet. It is also not pleasing from the scramblers' perspectives. From a more real stance, the foot is more prone to dermatological issues than the hands, which likely explains why I had to scramble a cube with a piece of skin on it...
2) Public image: 3x3 With Feet is viewed as a disgusting event by the public. Plain and simple. Along with Clock, the two events are commonly made fun of throughout the cubing community, and for an understandable reason. Again, as stated by the WCA and confirmed by one of many surveys, it is a highly unpopular event. Period.
If you still think that there are no real reasons to remove feet, then debating you is honestly hopeless.
