You can be against the actions that were done by a group of people 2000 years ago without being against their descendants today. First of all Jesus was a Jew so how can any Christian who is not an idiot (no shortage of those) hate all Jews without hating Jesus as well.
If He came to Earth with a mandate to save the Jews He failed. If we follow the Christian belief that he was infallable this becomes an oxymoron. His message fell on many deaf ears but his early followers were all Jews as well. Belief in Him as the "Only Son Of God" by people who all start their main prayer with "Our Father" also rings strange?
What was important to me about Christ was his teachings of peace and love of all others. I have little use for the dogma of any religion so I could be branded anti-_____ (fill in the blank)
