Where is Ahavas Yisrael?

Why can't we get along? Yesterday seemed like the perfect day.
I was in Hershey Park, and I was amazed at the cross section of Jews there. There were all types...chassidim, misnagdim, MO, women in shaitels, baseball hats, no hair covering, pants, etc...all having a wonderful time...mostly with families...it didn't seem, as many would believe, to be a "hangout" ...it was just a nice day, with Jewish music playing in the background to spend with fellow Jews.
