You mistake is assuming the law is being applied in good faith.
Of course hailing a tram is obviously different than a Nazi salute to anyone.
But the objective is not to detect Nazis , it’s to find an excuse to harass and intimidate people.
This is just another tool in their belt.
With a new law, you should always think of how it’s going to be like if applied by the most bigoted racist police officer in existence. And what mechanisms you have in place to stop that officer.
A stance of “Both sides are bad” is just a stance that favors the Status Quo.
The underdog needs the extra assistance, the superior doesn’t.
So for that reason I’m pro-Israel, don’t want either side winning, don’t want aid to either side, so that defaults to a pro-Israel stance.
I’m comfortable being labeled as such.
