"It would be so much easier if we just ask you about who belong a here or not."
.
Just to clarify: "easier" than what?
.
"What's your criteria [for those] who belong here or not?"
.
Those who espouse and practice classic principles of Liberalism: that is, the belief in the primacy of individual freedom and minimal government.  Those who respect other's most fundamental rights and privacy, and celebrate the men who enshrined those rights in our country's founding documents......I guess we can start there.  Does this help?
.
"I have a suspicion [about your criteria], but I'm afraid to say..."
.
It is troubling indeed when you're "afraid" to speak openly about your ideas and beliefs.  Men like Zuckerberg and their Leftist mentality represent the opposite of such ideals, and their opposition those ideals, along with the practice of speech and idea suppression, is rampant throughout that Leftist state.  Again-- those who embody such ideals have no place here.
