Hardly. Unlike our Protestant friends who put so much emphasis on the ability to read the bible, the TLM is so rich in symbolism from the structure of the church building, the altar, the vestments, to each and every action of the priest offering the Holy Sacrifice, the gospel is understandable to the illiterate.
You just reject the Catholic understanding, and it is very hard to come away from a TLM with a Protestant understanding of the gospel.
I will grant you the symbolism. I think that is a flaw in Protestant worship; too often we reject too much liturgy in my opinion and make things too simple, which destroys the mystery of worship and communion with God.
But, even so, the Christian should be able to understand EVERYTHING, every little minute detail, every little word said by the man leading the service.
Latin is not essential to the mass. You can say it in English and it would mean the same. I think the awe-inspiring atmosphere is enough to keep people centered. You don't need a language that could be a stumbling block.
