be less judgmental

Ok, so I’m a very religious person. The very stereotypical type of judgmental, right? I’m not a Bible thumper. I don’t get in people’s faces and tell them that they are going to hell or anything like that. I am judgmental in a more subtle way. I see certain situations or certain types of people and think to myself, “they can’t be up to any good at all.” I think I may be keeping myself from good friendships or relationships because of this. I think I need to broaden my horizons, but I think this might be hard to do without compromising who I am and what I believe is right.
