Step 3: ask Yourself what are the odds that someone has a doppelganger Hitler grandfather
Step 4: ask Yourself who in their right fucking mind would put a picture/ portrait of their grandfather if he looked just like Hitler..
Step 5: ask yourself; why would a grandfather who looked just like Hitler; why would he give himself that hairstyle and give himself that mustache ... Grandfather must have heard of Hitler... no ?
State of Israel was literally founded ( and Palestinian land taken/stolen) by Zionists.
