You won't be protesting in the U.S. without significant risks to your economic and social status. BTW - The Iraq war was several wars ago, and most of the people chatting here weren't even born for the first Iraq war.
2017 became the year the censors and suspensions of anti-social media started. Now with A.I. mods owned by an entitled parasitic elite, we get a highly censored world were your only recourse is offline, often in solitude.
If you care to test your theory, that you can criticise who you like in the U.S., I suggest you protest Israel, loudly and often.
