Peaceful protests are being quashed by the literal US military/national guard. There are videos of police specifically targeting people with signs/flags they don't like with "less lethals".
Before that campus protests calling for an end to genocide were quashed by local police.
People who attend either of these protests are being jailed and/or deported.
"Free speech" is a myth.
When you start equating expressions of solidarity using a flag of another country with literal Nazi flags, you might need to reconsider how far down the nationalist/facsist pipeline you are yourself.
Also I didn't say people could or couldn't wave Nazi flags today.
I said the Nazi regime doesn't care what flag you wave, you won't win their sympathy and be spared/stop their actions by waving their flag.
