I love how this thread became a big argument if Baltimore is a good city or not. I have relatives who currently live there and some who grew up there.
Any community outside of the NYC area is much more welcoming and non judgemental. I grew up outside of New York. In the Orthodox shul I went to, I had friends who were conservative and reform who went to the shul because the Rabbi and members were all kind and non judgemental. I’ve found that the larger the city, the more judgemental the people are. Saint Louis Park (Minneapolis suburb) was less judgemental than Chicago, which was less judgemental than New York. In the smaller communities people with different haskafic views are forced to interact with each other because of the limited amount of minyanim. In some shuls both the people wearing the knitted kippas and black hats will welcome other Jews wearing jeans and a t shirt because at the end of the day they realize that they all count equally towards a minyan.
Regarding Baltimore: None of my friends who grew up there would consider moving back to Baltimore to start a family. The crime does reach some of the Jewish areas. Its not a warzone like some other comments in this thread make it out to be. You just have to be aware that sometimes things can happen just like when you go through some parts of New York.
