old tongue

On the 21 febr, when i bought some food at a small turkish shop, three people were passing outside and looked directly at me.
The first one was a man on a bicycle, he gave me a firm look, his eyes didn't move as if they were glued into his skull.
He looked somewhat if he woud be under water.
The second one was a younger woman on a bicycle, she was wearing kind of combination of cap and scarf, of sand colour, that covered her face, despite it wasn't cold. Looked somewhat oriental.
The third one was an old woman, while she looked at me, she stuck out her tongue and moved it in an obscene way.
When she had passed, it did cost her some effort to move on, because she was so attached to me.
The obscene tongue-thing has been used before, always from people older than me, most of them older than 60, as usual more male than female, maybe two thirds or so.

On the 23rd febr, in the morning, when i was on my was to the baker, at the park, there was someone coming up to me, straight from the side. It was slightly raining, and there was no one else around.
I had to correct my course, to ensure that he would not walk/run into me.
It seems he thought of attacking me.
He wasn't tall, but looked fit, not older than me, short hair. somewhat darker(eyes, hair), olive parka.

When i was at the cheap supermarket that day, a young woman was passing outside. She was black, or partly black (x% ?, fair for a black), it seemed to me that she did not want to walk there, but had to do, she had such an expression in her face.
When i was outside, two or three man, maybe 50 years old, where passing me and looking in a cocky way at me, they were upset in a way, and maybe they thought they should be kind of authority. Maybe lefties.
Someone on the other side of the street said clearly "she is so uneducated, it's a shame !" ("ungebildet").

When i was at a bigger petrol station at that night, there were two black dressed men, petrol-station security.
The one looked similar to that guy in the morning, but taller, and more robust(more than most).
He said, he wanted me to hear this clearly :" you know, they are kanaks"( "kanacken" in german is (mostly) for turkish as the english "nigger" is for black, downlooking but by some of them used themselfes, he said :"weisst du, das sind da so Kanacken").
The way he lookes and speaks he would be a "kanak" himself.
These loudspeaking/directed speaking is often done from someone in companion of another one(or more), so it theoretically could come out of a conversation between them.
