When one understands WHY such practices were introduced, and the theological and liturgical errors they were meant to introduce, yes, they are a big problem.
Sean, you're playing hide the ball. You don't explain these alleged theological and liturgical errors, let alone demonstrate the "dialogue" mass has them.
The primary end (goal) of the liturgy is to worship God, but the liturgy also serves to educate and edify the faithful. The DM is a means to serve the secondary end of the liturgy. Now, it may be that some in the liturgical movement at the time overemphasized the secondary end of the liturgy, but that doesn't mean the DM is, in itself, wrong.
As an analogy, marriage has two ends. The primary end of marriage - children - does not exclude the secondary end - mutual support of the spouses. If in marriage classes a priest adds a module about mutual support, that module doesn't become a "problem" even if the priest added it due to wrong notions about the priority of the ends of marriage.
A more balanced view of DM would be to recognize that it is one means to serve a secondary end of the liturgy, and the most your arguments show is that perhaps DM shouldn't happen at every low mass. Which is, I think, consistent with using DM at school masses, or the once-a-week custom at Winona, as well as Matthew's post
here.So you can’t just dismiss aversion to the dialogue Mass as personal preference for quiet, or shrug shoulders and say, “What's the big deal?”
Your unbalanced view of DM does suggest something is going on. It could be personal preference, or something else.
Speaking of unbalanced views:

The article is telling traditional Catholics that the laity responding aloud during the mass (whether just singing the Kyrie or the Credo, or just responding "et cuм spiritu tuo") is a novelty of the 20th century, and not a custom of the Roman Rite.
(Byrne may not have said exactly that on that page, but she writes stuff like that in other pages on the TIA site.)
So singing is a novelty and not a custom of the Roman rite?
If the popes wanted the people to be quiet and not sing, you should be able to find where the popes said that.
