I find it beautiful. There was a video I saw of a guy in the US that started a hug campaign, and soon people were all hugging each other in the streets. Oddly enough, the police stopped the hug campaign, but after they collected thousands of protesting signatures, it was allowed to continue.
Open affection for others can be a wonderfully uplifting thing no matter what, but I also think that someone who attains spiritual growth to the extent that they truly love unconditionally probably also has a very strong energy to their presence that magnifies the experience and creates greater retention for the "huggee."
