Hit the brake pedoals, get off your pedoestal, and stop being so pedoestrian with your arguments.
Some of those actually derive from pedes, or walker, not directly from pes.
I think you'll find ped- is the prefix for foot, when followed by a vowel. Ometer is the suffix for a measuring device (thermOMETER, barOMETER, pedOMETER).
Are you serious?
Thermometer is literally thermo + meter, and barometer is báros + meter.
In any case, my original point was that pedo is the prefix for both foot and child, and even if this were referring to the child meaning, we're not gonna get rid of all words starting with pedo just because pedophilia is a thing.
