"MORE HASBARA HOGWASH"
You're not fooling anyone.
Your claim that you "...used to support Palestine" is a popular lie among the U.S. funded army of Full Time, paid and scripted Zionist shills with multiple usernames hired to deceive the gullible.
I dare you to show anywhere that individuals who are educated and ethical enough to condemn history's most heavily censored foreign funded genocide require anyone too "..be a leftist."
Go back to your Hasbara Handbook and "Global Language Dictionary" and try again.
