Can't believe some people still didn't read up on the situation in Syria.
It all depends who you are as a Syrian.
If you (your family, your ethnicity, your heritage, whatever) are Alawite, Christian, Druze and partly Kurdish then you are more likely to side with the regime. Because the regime was good to most of those ppl. (in terms of gov. jobs and such) - most of the security apparatus is non-Sunni, most officials who defected so far are btw. Sunni (I looked it up every time to reaffirm).
If you're Sunni (some 70% of the pop) then you very likely side with the rebels (or terrorists; depends on your perspective, obviously).
Sunnis are supposed to be more conservative, Islamist (according to a Syr-Chr. friend of mine, whom I studied with in US and who hasn't posted in a few weeks in FB..)
Also: in almost every rebel video you'll see Women fully clad in black, etc. so I assume this assessment is correct.
Assad's wife is also running around like that:
Sentry is
Druze btw.:
