Welcome, Michelle.
What a great hello post!
I'm having some trouble with anger myself this - just when I thought I had finally 'healed' my animosity towards Christians. Suddenly it has come back and seems like the correct attitude to have.
I think the correct response is to call out injustice where it is, and place the accountability on those who are actually responsible. That will direct the anger into productive, meaningful action, which will dissipate it. And maybe even make things better at the same time.
We need to call out those who have unleashed a storm of violence in CA and provided an atmosphere in which unstable individuals feel justified in hate-motivated assaults on gays (or any group.)
