I am basically from Malibu and my mom worked at Pepperdine. I lived in New York, which is not exactly not Philly, but I could definitely see a difference between East and West Coast. Different is not bad, but it is noticeable.
Anyways, I actually worked for a couple attorneys than went to Pepperdine and I could give you their e-mails if you wanted. In regards to the area Malibu is pretty yuppie and probably less tolerant of a gay student than the Bay Area would be, but L.A/Malibu is by no means intolerant. Malibu is technically in L.A., but L.A. is unlike any other city I have been in that it is so massive that having grown up there for 18 years I still don't know even know how to get around all of it. It just spreads out FOREVER and Malibu is at the very northern part of L.A. and a long drive to the city Parts of L.A. Westwood, Santa Monica etc where law firms and more tolerant people would live. I think Pepperdine is gorgeous, but a drawback would probably be it's location so far away from everything and it would be pretty hard to get to your internships etc. L.A. Traffic is horrible and you have to drive up this crazy canyon to even get to the freeway that connects to anything in L.A.
Honestly, if you are gay and moving out West I would think San Francisco would be an easier transition because I would say 30 to 40% of the people in the city are gay and it is also easier to get around because they have a public transportation system that L.A. does not have. I go to GGU in San Francisco and I have loved it so far and everything has worked out. If you have any questions about GGU I could answer them, but that is the only law school I know in depth to give any advice about. Honestly, when looking on boards like this a lot of people talk out of their ass about schools they have never been to and do not listen to it. Ask people that actually go to the school and get real insight. I can speak to the culture etc of Malibu, because I grew up around there, but I will not say anything positive or negative about the law school because I don't attend it.
