Yes, I understand that, however, if someone goes to France because they want to see DLP, I do not see anything wrong with that. In fact, I do understand the other side of it. That is why I tend to mock those that go to Florida and sequester themselves in the property of WDW.
What it boils down to is more of a fear of the unknown. If you're raised in a relatively sheltered life or grew up with a family that could not afford to travel, then you chose your destinations based on cost and comfort. I have read so many posts here where people are afraid. They are afraid of the traffic, afraid of getting lost, afraid of the area and the real and imagined dangers that exist out there. Afraid to explore anything other then the safe, security blanket feeling of a Disney park. They can then go home and cross Florida off the bucket list because they indeed spent time in Florida. They can also go to DLP and stay under that imaginary blanket and be able to tell their friends and relatives... "Hey, I went to France". They were able to do that without having to worry excessively about language barriers and making huge mistakes culturally.
Most people are also not overly interested in anything that slightly resembles history. They live strictly in the now and have no real interest in what others do or what they did in the past. Perhaps, a somewhat narrow way to live, but, one can go their entire life without ever seeing anything other then the town that they were born in and die perfectly happy.
