Blasphemy

Why is there no problem? Abroad, the street is secular, and in the opinion of non-Jews, seeing a group of people praying and making noise bothers them. They say, "They have a synagogue to go to, but I don't want to see people praying there." Not only is the noise bothering, but so is the sight. Religiosity is something private and shouldn't be advertised everywhere. Just as it bothers me if I'm walking down the street and see a group of people bowing on a carpet in the middle of the street.
Why don't you agree?

You live in France and I don't know the reality there. I know that there is great sensitivity there about the issue of separation of religion and state, especially in Berlin. That's why people oppose burqas in Berlin and on the beach, etc.
In my opinion, this is ugly anti-religious nonsense. It's nobody's business what I do in Berlin as long as it doesn't really bother him. If it bothers him ideologically, let him take a pill and get over it. If it's allowed to sing and dance and demonstrate and express opinions and have pride parades in Berlin, then it's also allowed to pray.

But doesn't blasphemy itself depend on ideological interference with another?
If I do something religious that bothers him, will it make him think "Oh, this is Judaism, here you see the Jews, etc.", and is that itself blasphemy? (Of course, there is common sense, if I'm just walking down the street and it bothers only him and it's not an accepted standard that something like this would bother, then it shouldn't be considered)

Absolutely not. Interfering with anti-Semites in your actual religious worship is not blasphemy. It is surrender to terrorism.
