Syag Lchochma, I hear your point about people arguing just because they are “hearing” something differently. And it is annoying when people get into stupid arguments about things. However, in this case, I do not agree with your take on the situation.
“I often see young adults or older girls shamusing ,laughing etc. right in middle the street when the men go and come from shul in the late evening. Wouldn”t it be appropiate if they would at least move to the side or against the wall and lower their tone of voice?”
If you look at his words and not just the “tone”, he writes that the girls should move to the side. It sounds like they are in the middle of the street in a place where the men have to walk on their way in and out of shul. It is inappropriate for girls to be standing right where men are walking out of shul. He writes that they should move to the side – he doesn’t say they should get off the street and go inside, just that they should have the courtesy to move to the side.
He also writes that they should lower their voices. It sounds like they are being very loud. I mean it is technically possible that they were talking in a regular tone of voice and he thinks that they should whisper, but I did not want to be judgmental and assume that he is the kind of person who thinks that girls have to whisper in public. If he were that kind of person, he probably would have said that they should stop talking in the street which is not what he said.
