Of course, sometimes the language barrier extends beyond just a new way of saying words.
There are some words that are completely different in the US, and some that have entirely different meanings. Both of these are extreme stereotypes that completely polarise a hugely interesting and diverse culture.
One criticism that is constantly levelled against American women, is that they expect perfection.
Perhaps that they have not found the person they are looking for yet. Either way, in my experience, Chelsea does not expect perfection. This, from what I have experienced, seems to actually be somewhat true.
Perhaps it is the novelty of hearing something new that makes accents so appealing.
I imagine this criticism comes from a handful of scorned men, with somewhat limited dating experience, and have become bitter towards all, based on the actions of a few.
It is very easy, from a few experiences, to label a group of people as the same, yet ignore the diversity within the group.
I also think that people with this view tend to fall into the trap of feeling that the grass is greener on the other side.
