Entropy and Identity

I shall first begin by responding to Water Closet and then proceed to speak about X Marks the Spot in a later blog post. The underlying idea behind Water Closet seems to be that of the entropy of identity through means of communication, by compromising our individuality in order to connect at some level with another being. Bataille speaks about the human being as "dissolved in 'strong communication,' by opening a tear in himself through which he loses 'a part of his own being to the profit of the communal being." (pg. 205) This degradation of individuality breaks down into uniformity. Then he goes on to talk about Genet's train experience, or realization in which he and another traveler became the same person, upon peering into each others' eyes. "The identity of the self is canceled in this revelation. The self is disseminated, since if all men equal one another, 'each man is every other man.' No man was my brother:each man was myself, but temporarily isolated in his individual skin." (pg. 207) Now, is he talking about our individuality as being purely superficial, and aside from physical appearance, we as humans are all the same? So, the breaking down of our individuality can also be an unspoken communication?
I don't know what the idea behind Trailing is. The point seems to be nothing more than the bond between a subject and object, forming something by beginning with nothing, going through some process, and ending with nothing. I am confused as to what message I am supposed to understand from this idea or process of Trailing.
