The fact that Sarek can spread his emotional condition to infect an entire ship's complement, that Spock can host his consciousness in another person, that Sakkath was able to use his own mind to settle Sarek's, that katras themselves can be hosted in other people or vessels permanently, that a mindmeld leaves a permanent imprint of those people on one another, leads me to suspect that Vulcans are among the most powerful telepaths in the entire franchise. We just never see them featured that way really
And that they don't engage in routine telepathy like for example Lwaxana Troi does, seems less like it's about respect for those who can't, & more like another aspect of their discipline, that they might actually see it as a frivolous or lowly use of that skill, & so deliberately refrain from allowing themselves to do it.
I mean, as elitist, & haughty as they can be, would it really surprise anyone that Vulcans might consider constantly knowing the thoughts of others rather vulgar? Personally, what I think they might have a respect for is the sanctity, & majesty of the mind, such that they'd not sully their gift to share them, like it's some kind of basic olfactory sense. "Ooo! I smell fear & deception!" What Vulcan is going to want to be so crass as to tramps around in minds like that? I'd think they'd train to be the very opposite of that, such that it might even have become foreign to them.
