Isnt life all about making choices and having preferences ? This topic has been discussed so many times on this site.... That's why the term "Shopping" was invented..
You search for the things you like and want. While the guy may have been a bit crude with his reply, and could have framed it better, dont give him so much heat about it. He was simply excercising his right to "choice", which is something WE all do when "shopping" for our companions.... While it may not seem so, YOU Mr @Smurofare "rejecting" the people you view and pass over, while it may not be as direct a rejection, IT IS REJECTION.
In situations like this where someone turns down your advances, its always best to just move on. Where one door closes, another one Opens.... the less said the better.
