If there is no punishment for doing it they will do it and keep doing it as frequently as they can.
Edit are these people stupid? Trump banned then from entering the country and regukay tries to stir up-racist tensions against Muslims in general why would they think he could possibly be better on this issue? The guy literally said he wanted Israel to speed up its disastrous campaign it makes no sense to me.
I can have conversations with strangers without much difficulty. I have no choice and people are uncomfortable if I am silent in a lot of scenarios. I identify common ground with the person typically based on where we are meeting and if I don’t intend to connect to the person I keep conversation general and don’t ask names unless it seems like I may run into this person again. I then forget that name probably but it’s nice to ask.
