Don't be. NJ is one of the most diverse places in the country, very blue, and very highly educated. The more rural counties in the northwest of the state and Monmouth/Ocean Counties are pretty uh...Trumpy, but most of the state is not.

Oh my sweet summer child

> I'm not the.. straightest person around. How bad is that taken within the state

Again, NJ is very diverse and accepting. Sure there are shitty racists/homophobes anywhere, but you definitely won't find that's the norm here.
