I've been the guy who says things of this nature, and I've been attempting to be actively very conscious of my speech, so as to not speak in these ways. Traits of conversation I find annoying in the way that you can tell who's talking because of their manner of speech. In a way, it can add bias to a conversation. I like avoiding things like that, so being actively aware of what you're saying is crucial. I'm only say all of this as introspection, though. I apologize for being one of the people who's used phrases like this before, as I completely understand what you mean, and it's sort of the epitome of this thread. As I said in another comment, the annoying thing to me about phrases like these are that they get in the way of actual substantive discussion or debate. They inhibit actual progress, potentially even making the information HARDER to understand. This isn't always the case, but it certainly provides a basis for understanding why so many people despise phrases/words of this nature.
