User blog:LurkerLordB/Survival of the Cathars

OK, I was learning about the Cathars via the almighty Wikipedia, and I began to wonder if it would be remotely plausible for them to survive (and possibly even flourish). I have three questions which I am having trouble answering:

1. Is there any way you could think of for Catharism to survive from its beginning to the present day, even if it means staying in small numbers like Zoroastrianism?

2. Would it be possible, if #1 happened, for the Cathars to eventually become a major religious group, that is widespread over many countrie?. This could be either right after the POD, or it could be small until some great revival.

3. Would it be plausible for some time in history for a Cathar revivalist movement to occur, even if #1 didn't happen and they were wiped out like in OTL?
