Brother Cobalt,
Simply to confirm my POV, I am also a Christ follower.
I don't believe we have any ground to stand on and say we expect people to treat us better, with more respect or love because WE are a Christian. That sounds like the prayer of a Pharisee.
Instead, it should expect that WE TREAT ALL OTHERS better, and with more respect and with more love because we are a Christian.
The only time WE can hold people accountable for their behaviour is when they profess to be Christians with their mouths but not their lives. Read through James again.
Also, as you stated, in scripture we are told we will be persecuted for our faith. It also says to consider ourselves blessed when this happens. I'm sceptical that our Lord who was beaten and crucified on the cross was talking about getting hurtful emails...but maybe I'm wrong.
It's about how we show Christ's love to others, not how we expect them to respect us -- especially considering how many "christians" have given the world good reason to doubt, fear and hate people who use that title.
It is also worth asking ourselves if WE HAVE BEEN Christ-like in our service and love of others - including friends and enemies. I can admit I have not always been good at this, and that's why there is the promise of forgiveness from God--but forgiveness from the ones we hurt must be sought from them.
If you haven't already, I would also suggest re-reading Matthew 5, especially (but NOT exclusively) verses 43-48.
Grace and peace,
