I can't help you with similar places to 4-ch. But I can give you this advice - don't assume that all the people where you live are retarded and shallow. Sure, maybe 99.9% of them are, but if you don't give up, eventually you'll find at least one person on your level. Moving to a new place sucks, I've done it quite a few times through my life. It might take a while to get accustomed, but it will happen eventually even if you don't expect it.
For me, it took 3 years to really find people that I connect with here. That's a really long time, but I was stubborn and refusing to move on with my life. Hopefully it won't take you that long to adjust. 3 years was how long it took for me to realize that the internet is great, but only to a point...
