@bombastic Bob Re: stupid politics
First, how many of the IETF members are coming from those 6 countries ?
So... while you are right that the IETF may be making a political statement, its also possible that they fear that a member could be blocked from travel.
But I will speculate a third reason... they are afraid of getting attacked by a group of rogue Antifa members and accused of being Nazis because they dress differently.
And that makes me wonder.... Is Antifa which is supposed to be against fascism yet acts more like a group of fascist black shirts, all just a fascist hipster attempt at being ironic?
