I've noticed that there are a huge amount of people on the Internet who are VERY concerned about lineage when it comes to Kung Fu schools.
I first got on an email list back in 1997 that was devoted to Kung Fu specifically. I mentioned that I studied Shaolin Lohan Kung Fu and was immediately set upon by several responders who basically dismissed my statement as too general. They demanded that I provide lineage holders for my system to back up my claim and quickly moved to suggest that I probably wasn't taking a real system at all!
By the time I had started responding I had already been dismissed by these people, most of whom indicated they were instructors or high ranking members of their particular style. When I finally got a reasonable response from some of the members it was to indicate that they had had a few people trolling their email list who weren't what they said they were, hence the knee-jerk reaction. At the time though the explanation didn't really matter as I had already been quite put out by the whole experience and soon after dropped out of that list.
