I agree with your statement. Being pro-Israel does not conclude vice versa. As you stated, everyone has their own biases. However, I also believe that negligence of facts and truth can be hazardous. Such a statement shouldn’t even be normal. When looking at what Israel has done and is doing, you’ll realize that they actually support Palestine more than most of the Palestinians themselves. When you look at the sacrifices that Israel has made by giving away the Golan heights, etc, it’ll surprise you to see someone still not understanding that the main issue is not Israel.
