I think the quotes in your post should be around "more practical" and not just "practical" (I changed the bolding and underlining from your quote of my post).
According to Google, the word practical means: "of or concerned with the actual doing or use of something rather than with theory and ideas"
I think it's pretty clear that engineering and medicine (which are about the implementation of our understanding of physical and biological sciences, respectively) are by definition "more practical" than the humanities. But, I'm open to listening to arguments to the contrary.
For what it's worth, I specifically chose engineering and medicine because I think they are also more practical than other physical sciences like theoretical physics and biochemistry (which I think are more about understanding "theory and ideas").
It also seems that your post suggests you believe that "not as practical" means "not as good". I didn't say that, but maybe that's your "strong bias" :). My thought was that people who may be anti-education probably appreciate it when people are designing them better tools and treating their ailments.
I think you missed my point. Your clear implication is that engineering or medicine are more practical than a degree in liberal arts. My point is that many liberal arts degrees can be practical, and some liberal arts degrees may be more practical than other engineering or medicine degrees.
Maybe I still don't understand what you're trying to say.
Here's how I see our conversation:
I said: Engineering and Medicine are more practical than the liberal arts so people who typically don't see education as a positive might not view those with education in these fields as negative.
I think you said: I have a "strong bias" against liberal arts education because they can be practical too.
I said: (1) I used the words "more practical" and I think it's true that engineering and medicine specifically are more practical than the humanities. I believe that there are practical aspects to the humanities, but I also believe that engineering and medicine are almost entirely focused on the practical implementation of theoretical knowledge. I also pointed out that this is not the case for other physical sciences that are more interested in theory than practice. (2) I also feel that you think when I say that something is "more practical" I'm also saying that it's "better", where I literally mean that it's more practical.
I think you said: The liberal arts can be practical, sometimes even more practical than engineering and medicine.
I agree with the first part, which is why I originally said "more practical" and why I think you omitting the "more" in your quote didn't capture what I said. I don't agree with the second part but I'm open to being persuaded.-----
I think I understand the point that you're trying to make (if it's that some liberal arts degrees are more practical than engineering and medicine). But, I don't agree with it. Like GuitarStv, I'd be interested in hearing you flesh that out a bit. I'm open to being persuaded, but as of now I don't think what I said is incorrect. I think it's especially true in the context of the original discussion (how people with disdain for education view those fields).
I would agree with you if your statement was something like: some of the humanities are more practical than some of physical sciences. Some of the physical sciences are very theoretical (e.g. theoretical physics). Again, being less practical doesn't make something bad.
