As a simple example, there was an employee of a TV news station in Moscow that started screaming pro-Ukraine things on the air, on live TV. She was given a 100 ruble fine (for causing a disturbance) and released.
Meanwhile, people in the EU are actually imprisoned for supporting Russia. And of course Ukraine has death squads, and merely being accused of supporting Russia or being accused of speaking Russian is enough to end up in one of the filtration camps.
The two situations are not comparable at all.
I’d suggest you find better new sources because I have seen the videos of the people being hauled off by the Russian police for holding a blank sign where as your example does not even exist.
Here’s an example

How do you mesh this with the fact that you can and will be arrested in Russia for calling the war in Ukraine a war, or for even protesting with a blank sign?.
