Do you really have to ask this question? Don't you know the answer? "Why, when a creator such as myself is against the violence on both sides and supports Israel's right to defend itself, I’m called a Nazi?"
There are bad people out there. They are not interest in a proper discussion. There are people like that on all sides on almost any issue. If you post messages or write stories about anything controversial someone will call you a NAZI.
Regarding "supports Israel's right to defend itself." I support Israel's right to defend itself but I also suggest that in doing so it stay within the limits of current international law.
